President-elect Donald Trump sent out shockwaves on Thursday by tweeting that "the United States must greatly strengthen and expand its nuclear capability," but spokesman Jason Miller later tried to temper the statement, explaining that "Trump was referring to the threat of nuclear proliferation and the critical need to prevent it," and maybe "the need to improve and modernize our deterrent capability." On Friday morning, in a phone call with Morning Joe's Mika Brzezinski, Trump reportedly clarified that, no, he really meant he's game to replay the Cold War.

"Let it be an arms race, we will outmatch them at every pass," Brzezinski quoted Trump as saying, "and outlast them all." "All right, you can put that down as breaking news," said co-host Joe Scarborough.

In his annual press conference on Friday, before Morning Joe aired, Russian President Vladimir Putin said that he wasn't surprised by Trump's tweet because "during his election campaign he said the U.S. needs to bolster its nuclear capabilities and its armed forces in general." But Russia is not seeking a new arms race, or developing new nuclear warheads, he added. But it is working to improve its armaments to ensure they'll break through missile defenses. President Obama and Russia negotiated a reduction of nuclear arms, the New START treaty, in 2011, and Putin said Russia would keep its nuclear weapons inside the limits of existing treaties.

The problem with Trump's tweets, David Ignatius said on Morning Joe, is that while he may be seeking to throw people off balance, "when he gets cornered" on a controversial statement — like scrapping the one-China policy — "he sometimes doubles down. And I think that's the thing that, as I talk to world leaders, foreign policy veterans who've served in Republican administrations, they worry about this." Trump is painting the U.S. into a corner, and himself, too, Ignatius said. "If you say, 'What I really do want is an arms race,' you're going to lose the country. The country doesn't want to go through a nuclear arms race." And as of Friday morning, Russia didn't either. Peter Weber

House Judiciary Committee Chair Jerrold Nadler (D-N.Y.) warned former White House Counsel Don McGahn on Monday night that if he ignores a congressional subpoena and refuses to testify before his panel on Tuesday, "the committee is prepared to use all enforcement mechanisms at its disposal."

Earlier Monday, White House Counsel Pat Cipollone notified Nadler that Trump had instructed McGahn to ignore the subpoena and skip the hearing. In a letter to McGahn, Nadler said "President Trump's order — which seeks to block a former official from informing a coequal branch of government about his own misconduct — is unprecedented," adding that this "does not excuse your obligation to appear before the committee."

Nadler listed several reasons why Trump cannot keep McGahn from testifying, including that "the president himself has already called your credibility into question." Nadler is referring to Trump tweeting earlier this month he "was NOT going to fire Bob Mueller," contradicting what McGahn told Special Counsel Robert Mueller. "In attacking your credibility and asking you to make public comments about these events, the president has not only further waived any possible privilege with regard to your testimony; he has also created substantial concerns about acts of witness intimidation and further obstruction of Congress' ongoing investigations," Nadler said.

Kris Kobach has a long list of demands for a job that doesn't even exist yet, three people with knowledge of his requests told The New York Times.

The former Kansas Secretary of State was approached by President Trump in April after former Homeland Security Secretary Kirstjen Nielsen resigned, the Times reports. Trump wanted to know if Kobach, an immigration hardliner, might be interested in the position. Trump was concerned that the Senate would not confirm Kobach, so they talked about making an "immigration czar" position. Trump hasn't yet decided if he'll create the role — and if he does, he hasn't settled on hiring Kobach, the Times reports.

Following the meeting, Kobach got to work putting together 10 conditions for his employment, people with knowledge of the matter said. His demands shocked White House staffers: among other things, he asked for an office in the West Wing; weekends off; 24/7 access to a government jet; the ability to walk into the Oval Office whenever he wants; a staff of seven; the title "assistant to the president," at the highest pay grade; and a guarantee that all cabinet secretaries who have anything to do with immigration policy defer to him, the Times reports. Kobach also wants Trump's promise he will nominate him for Department of Homeland Security Secretary by Nov. 1, unless Kobach asks to remain immigration czar.

Kobach, who lost the Kansas governor's race last year, was tasked by Trump to lead a voter fraud commission launched after Trump baselessly claimed millions of illegal votes were cast in the 2016 election. The committee was dissolved last year. Catherine Garcia

Air Force One is about to rack up a bunch of miles between D.C. and Pennsylvania.

During a rally on Monday night in Montoursville, President Trump promised that he would be "seeing a lot of you over the next year. I'll be here a lot. Got to win this state. We've got to win this state. We did great last time." Pennsylvania's 12th congressional district is holding a special election on Tuesday, and Trump was in Montoursville to campaign for Republican Fred Keller, who is running against Democrat Marc Friedenberg. Trump told the crowd he views the special election as "a referendum" on his presidency.

Trump won Pennsylvania and its 20 electoral votes in 2016. It's not surprising that Trump plans on visiting the state as often as he can: Earlier Monday, Politico reported that his own polling shows he's trailing behind former Vice President Joe Biden in Pennsylvania, Michigan, and Wisconsin.

Attorney General William Barr is pushing back against criticism that he is using his position to protect President Trump.

During an interview with The Wall Street Journal on Monday, Barr said that before becoming Trump's attorney general, he saw the president was the focus of several investigations, and felt "the rules were being changed to hurt Trump, and I thought it was damaging for the presidency over the long haul."

Barr wrote a 19-page memo to the Department of Justice last year, saying Special Counsel Robert Mueller's obstruction inquiry hurt the presidency; after the report was released, Barr decided that several incidents of potential obstruction described in Mueller's report were not criminal. "At every grave juncture the presidency has done what it is supposed to do, which is to provide leadership and direction," Barr said. "If you destroy the presidency and make it an errand boy for Congress, we're going to be a much weaker and more divided nation."

Barr's critics have called him out for refusing to turn over an unredacted copy of Mueller's report to the House Judiciary Committee, which led to the panel voting to hold him in contempt; ordering a review into the origins of the Russia investigation; and telling lawmakers that Trump campaign associates were the victims of "spying." All of this is "an affront to everyone who worked on that case and who supported it, and to everyone who works counterintelligence in general," former top FBI counterintelligence agent Frank Montoya told the Journal.

During a closed-door hearing earlier this year, President Trump's former personal attorney Michael Cohen told the House Intelligence Committee that Trump's lawyer Jay Sekulow instructed him to lie to Congress in 2017 regarding negotiations to build a Trump Tower in Moscow, people familiar with his testimony told The Washington Post on Monday.

Cohen launched the Moscow project in September 2015, and told Congress discussions ended in January 2016; he later admitted the negotiations continued into June 2016. Cohen said he lied to help obscure the fact that while Trump was running for president, he was involved in a project with potentially hundreds of millions of dollars at stake. He is now in prison for lying to Congress, campaign finance violations, and financial crimes.

During his private testimony, Cohen told lawmakers Sekulow encouraged him to say negotiations ended on Jan. 31, 2016, since the Iowa caucuses were on Feb. 1, the Post reports. Sekulow joined Trump's legal team following the election, and the Post notes it's not clear how much Sekulow actually knew about the Trump Tower Moscow project. Sekulow's attorneys told the Post relying on Cohen's word "defies logic, well-established law, and common sense." House Intelligence Committee Chair Adam Schiff (D-Calif.) said his panel is now investigating whether Sekulow or any of Trump's other attorneys "participated in the false testimony" Cohen gave to lawmakers.

President Trump's attempt to block a subpoena from House Democrats has been overruled.

Washington, D.C. District Court Judge Amit Mehta ruled Monday that Trump could not block the House Oversight Committee's subpoena of his financial records from his accounting firm. Mehta also denied Trump's lawyers' request to stay the ruling, meaning the firm is now supposed to hand over eight years' worth of Trump's records, Politico reports.

House Oversight Chair Elijah Cummings (D-Md.) subpoenaed Trump's accounting firm last month as part of Democrats' ongoing attempts to access the president's tax returns. He asked for the records first, but officially subpoenaed them after Trump's former lawyer Michael Cohen testified that the president had inflated his wealth on past financial statements. Trump quickly sued Cummings in return.

Trump's lawyers' argument revolved around claiming Congress' records requests were made for "a law-enforcement purpose" rather than "to work on legislation." Yet in the process, those lawyers implied the Whitewater and Watergate investigations were invalid, leaving Mehta visibily skeptical.

In his Monday ruling, Mehta said "it is not for the court to question whether the committee's actions are truly motivated by political considerations" and ruled in the committee's favor. Trump's lawyers are expected to appeal the decision immediately, setting it up for a decision in a circuit court.

In another subpoena-blocking move, Trump also sued a few banks to stop them from handing over his financial records as well. That suit is still ongoing in a Manhattan court. The Week Staff
