Trump's concede-nothing defense

• The document calls the articles of impeachment "constitutionally invalid on their face," and "a dangerous ... brazen and unlawful attempt to overturn the results of the 2016 election and interfere with the 2020 election."

The length and tone contrast with the 111-page, 319-footnote "Trial Memorandum" by the seven Dems who are House impeachment managers.

• "The evidence overwhelmingly establishes that he is guilty," the Democrats write. "The only remaining question is whether the members of the Senate will accept and carry out the responsibility placed on them by the Framers of our Constitution and their constitutional Oaths."
• "President Trump's conduct is the Framers’ worst nightmare."

Why it matters: The Trump lawyers' blanket statements, and the brevity of their arguments, suggest they have confidence that the Senate Republicans won’t let the president down when their big loyalty test comes.

• Smart brevity on the strategy: Concede nothing, admit nothing, apologize for nothing. Talk for TV. And don’t get into the weeds.

🥊 The most extraordinary line from the document, "THE HONORABLE DONALD J. TRUMP, PRESIDENT OF THE UNITED STATES, HEREBY RESPONDS":

• "The President's actions on the July 25, 2019, telephone call with President Volodymyr Zelenskyy of Ukraine ... were constitutional, perfectly legal, completely appropriate, and taken in furtherance of our national interest."

Reality check: The Government Accountability Office found that the administration broke the law by withholding Ukraine aid — funds that impeachment witnesses said were in the interest of U.S. national security.

• Witnesses argued that the campaign to pressure Ukraine to investigate the Bidens was a "domestic political errand," as Fiona Hill put it.
• Rudy himself has said he was acting as the president's personal agent.
