Former President Donald Trump’s lawyers and aides have turned down an invite from House impeachment managers for Trump to testify in his upcoming Senate trial. “The President will not testify in an unconstitutional proceeding,” adviser Jason Miller told The Daily Beast.

Lead impeachment manager Rep. Jamie Raskin (D-MD) had sent a written invite to Trump to testify under oath about his conduct on Jan. 6. If Trump chose not to testify, it would allow for “a strong adverse inference regarding your actions (and inaction) on January 6,” wrote Raskin. In a letter of reply, Trump’s legal team called the invitation a “PR stunt” and wrote, “Your letter only confirms what is known to everyone: you cannot prove your allegations.”
