It continued: “Without waiting to see what was actually said on the call, a press conference was held announcing an ‘impeachment inquiry’ based on falsehoods and misinformation about the call.”

Despite Pelosi’s claim that there was no “House precedent that the whole House vote before proceeding with an impeachment inquiry,” several previous impeachment inquiries have been launched only by a full vote of the House — including the impeachment proceedings concerning former Presidents Andrew Johnson, Richard Nixon and Bill Clinton.

White House officials told Fox News the vote opening the proceedings was a small ask, considering the implications of potentially overturning a national election.

Responding to the letter, Pelosi accused Trump of “trying to make lawlessness a virtue” and added, “The American people have already heard the President’s own words – ‘do us a favor, though.’” (That line, from a transcript of Trump’s call with Ukraine’s leader, in reality referred to Trump’s request for Ukraine to assist in an investigation into 2016 election interference, and did not relate to Biden.)

Pelosi continued: “This letter is manifestly wrong, and is simply another unlawful attempt to hide the facts of the Trump Administration’s brazen efforts to pressure foreign powers to intervene in the 2020 elections. … The White House should be warned that continued efforts to hide the truth of the President’s abuse of power from the American people will be regarded as further evidence of obstruction. Mr. President, you are not above the law.  You will be held accountable.”

Just before Pelosi took the microphone on Tuesday, a spokesperson for House Minority Leader Kevin McCarthy’s office emphasized some of the White House’s other objections to Democrats’ inquiry.

Separately, the letter asserted multiple alleged violations of the president’s due-process rights. It noted that under current impeachment inquiry proceedings, Democrats were not allowing presidential or State Department counsel to be present.

Among the GOP’s complaints are that Democrats’ procedures did not provide for the “disclosure of all evidence favorable to the president and all evidence bearing on the credibility of witnesses called to testify in the inquiry,” according to the White House. And “the right to see all evidence, to present evidence, to call witnesses, to have counsel present at all hearings, to cross-examine all witnesses, to make objections relating to the examination of witnesses or the admissibility of testimony and evidence, and to respond to evidence and testimony” has also been obstructed.

The White House asserted that Democrats also have not permitted Republicans in the minority to issue subpoenas, contradicting the “standard, bipartisan practice in all recent resolutions authorizing presidential impeachment inquiries.”
