By the authority vested in me as President by the Constitution and the laws of the United States, after carefully considering the reports submitted to the Congress by the Energy Information Administration, including the report submitted in October 2019, and other relevant factors, including global economic conditions, increased oil production by certain countries, the global level of spare petroleum production capacity, and the availability of strategic reserves, I determine, pursuant to section 1245(d)(4)(B) and (C) of the National Defense Authorization Act for Fiscal Year 2012, Public Law 112-81, and consistent with prior determinations, that there is a sufficient supply of petroleum and petroleum products from countries other than Iran to permit a significant reduction in the volume of petroleum and petroleum products purchased from Iran by or through foreign financial institutions.

Democrats keep their witnesses locked behind secure doors, then flood the press with carefully sculpted leaks and accusations, driving the Trump-corruption narrative. And so the party goes, galloping toward an impeachment vote that would overturn the will of the American voterson a case built in secret.
Conservative commentators keep noting that Mrs. Pelosis refusal to hold a vote on the House floor to authorize an official impeachment inquiry helps her caucuss vulnerable members evade accountability. But theres a more practical and uglier reason for Democrats to skip the formalities. Normally an authorization vote would be followed by official rules on how the inquiry would proceed. Under todays process, Mr. Schiff gets to make up the rules as he goes along. Behold the Lord High Impeacher.
Democrats view control over the narrative as essential, having learned from their Russia-collusion escapade the perils of transparency. They banked on special counsel Robert Muellers investigation proving impeachment fodder, but got truth-bombed. Their subsequent open hearings on the subjectfeaturing Michael Cohen, Mr. Mueller and Corey Lewandowski were, for the Democrats, embarrassing spectacles, at which Republicans punched gaping holes in their story line.
Mr. Schiff is making sure that doesnt happen again; hell present the story, on his terms. His rules mean he can issue that controlling decree about only one transcript and Democratic staff supervision of Republican members. It means he can bar the public, the press and even fellow representatives from hearings, even though theyre unclassified.

Unemployment today is at a 50-year low. There are more Americans working today than ever before. Median household income in the last two and half years has risen by more than $5,000. And that doesnt even account for the savings from the Presidents tax cuts or energy reforms for working families.
Because of the Presidents policies, America has added trillions of dollars of wealth to our economy while Chinas economy continues to fall behind.
To level the playing field for the American worker against unethical trade practices, President Trump levied tariffs on $250 billion in Chinese goods in 2018. And earlier this year, the President announced we would place tariffs on another $300 billion of Chinese goods if significant issues in our trading relationship were not resolved by December of this year.

s = '''
Needless to say, we see it very differently. Despite the great power competition that is underway, and Americas growing strength, we want better for China. Thats why, for the first time in decades, under President Donald Trumps leadership, the United States is treating Chinas leaders exactly how the leaders of any great world power should be treated with respect, yes, but also with consistency and candor.

Brexit is the scheduled withdrawal of the United Kingdom from the European Union. Following a June 2016 referendum, in which 51.9% voted to leave, the UK government formally announced the country's withdrawal in March 2017, starting a two-year process that was due to conclude with the UK withdrawing on 29 March 2019. As the UK parliament thrice voted against the negotiated withdrawal agreement, that deadline has been extended twice, and is currently 31 October 2019. The Benn Act, passed in September 2019, requires the government to seek a third extension.
'''
s = '''
The argument for Brexit
According to the BBC, the push to leave the EU was advocated mostly by the UK Independence Party and was not supported by the Prime Minister, David Cameron. Members of the UK Independence Party argued that Britains participation in the EU was a restrictive element for the country.
As one of the EUs primary initiatives is free movement within the region the partys main arguments centered around regaining border control and reclaiming business rights. In addition, supporters of Brexit cited the high EU membership fees as a negative aspect of participation in the EU. It was argued that if the UK separates itself from the EU, these fees can be used to benefit the UK.
The argument against Brexit
The Conservative Party and the Prime Minister were strongly in favor of remaining with the EU. As a result of the decision to discontinue its participation in the EU, the Prime Minister has made a public statement that he will be relinquishing his position. He believes that the country needs a leader with the same goals as the majority of the country. He has promised a new PM will be in place by early September.
The argument against Brexit pertains mostly to the business benefits. The argument is that the UK receives business benefits by being able to participate in the single market system established by the EU. In response to the criticism against the open borders, proponents believe that the influx of immigrants helps develop an eager workforce and fuels public service projects.
Leaders in favor of staying also worry about the political backlash that could possibly result from other countries who favored staying with the EU. In addition, proponents of remaining with the EU believe that being part of a wider community of nations provides economic and cultural strength, as well as an additional element of security.
What does Brexit mean for the future?
While the decision marked a huge statement for the UK, the referendum vote is not legally binding. There are still many hurdles that must be dealt with before Brexit can become a reality.
The UK is still subject to the laws of the EU until Britains exit becomes legal. In order for the UK to make its break official, the country needs to invoke Article 50. It is unclear exactly what this process will entail or how long it will take as Britain is the first country to take its leave of the EU. Once Article 50 has been formally invoked, the UK has two years to negotiate its departure with the other member states. But according to the BBC, Extricating the UK from the EU will be extremely complex, and the process could drag on longer than that.
Amidst the aftermath of this shocking referendum vote, there is great uncertainty as political leaders decide what this means for the UK.

LONDON British Prime Minister Boris Johnson said Thursday he will likely ask Parliament to approve an election as part of an effort to break a Brexit deadlock.
It is not clear if the vote, which Johnson wants to hold on Dec. 12, will take place as opposition lawmakers must also back the move.
They are expected to vote on the measure on Monday.
Johnson's announcement comes ahead of an expected decision Friday from the European Union over whether to delay Britain's exit from the bloc for three months.
Britain's leader has been steadfastly opposed to any extension to the nation's scheduled Oct. 31 departure date from the EU, although in a letter to the leader of the opposition Labour Party this week he said he would accept a short technical postponement, "say to 15 or 30 November," to allow lawmakers to implement an EU withdrawal bill.
Johnson's decision to offer to call an election follows lawmakers' rejection of his plan to rush through an EU exit bill that runs to hundreds of pages in just three days. They want more time to scrutinize the legislation and to make sure it does not leave the door open to a possible "no-deal" Brexit during future exit negotiations with the EU that will run through next year. A "no-deal" Brexit could dramatically harm Britain's economy.
The prime minister was forced to ask for an extension to Britain's EU departure date after Britain's Parliament passed a law to ward off the threat of a "no-deal" Brexit.
Johnson has repeatedly pledged to finalize the first stage, a transition deal, of Britain's EU divorce battle by Oct. 31. A second stage will involve negotiating its future relationship with the EU on trade, security and other salient issues.

Thank you very much. We have a Cabinet meeting. Well have a few questions after grace. And, if you would, Ben, please do the honors.
THE PRESIDENT: All right, thank you, Ben. That was a great job. Appreciate it.
The economy is doing fantastically well. Its getting very close to another record. Weve had many records since we won office. Were getting very close to another record. I dont know if anybody saw it: The household median income for eight years of President Bush, it rose $400. For eight years of President Obama, it rose $975. And for two and half years of President Trump they have it down as two and a half years it rose $5,000, not including $2,000 for taxes. So it rose, lets say, $7,000. So in two and a half years, were up $7,000, compared to $1,000, compared to $400. And thats for eight years and eight years.
Thats a number that just came out, but thats a number that I dont know how there could be any dispute or any Ive never heard a number like that, meaning the economy is doing fantastically well.
We need for our farmers, our manufacturers, for, frankly, unions and non-unions, we need USMCA to be voted on. If its voted on, itll pass. Its up to Nancy Pelosi to put it up. If she puts it up, its going to pass. Its going to be very bipartisan. Its something thats very much needed. Itll be hundreds of thousands of jobs.
