House Speaker Nancy Pelosi (D-Calif.) told Democrats in a closed-door meeting Tuesday that she will not send articles of impeachment to the Senate until she learns more about how the chamber would conduct a potential trial, according to three people present for her remarks who were not authorized to comment publicly.

The news came hours after Senate Majority Leader Mitch McConnell (R-Ky.) said that Republicans have enough votes to proceed with President Trump’s impeachment trial with no agreement with Democrats on witnesses.

Earlier Tuesday, Trump highlighted objections to the prospect of testimony from former national security adviser John Bolton, as Bolton’s announcement that he is prepared to appear at a trial continued to roil Capitol Hill.

The crux of the Democrats’ case is the allegation that Trump tried to leverage a White House meeting and military aid, sought by Ukraine to combat Russian military aggression, to pressure Ukrainian President Volodymyr Zelensky to launch an investigation of former vice president Joe Biden and his son Hunter Biden, as well as a probe of an unfounded theory that Kyiv conspired with Democrats to interfere in the 2016 presidential election.

●Bolton’s willingness to testify in Trump’s impeachment trial ramps up pressure on Senate Republicans.

●Bolton says he would testify to the Senate. So why not the House?
