Former Vice President Joseph R. Biden Jr. will call on Tuesday for impeachment proceedings against President Trump if the president does not comply with congressional requests for information related to Ukraine and other investigations.
In a speech scheduled for 2:30 p.m. in Wilmington, Del., Mr. Biden will “make the point that Trump’s latest abuses are on top of all of his prior abuses,” a campaign aide said. The aide said that Mr. Biden would call on the president to comply with “all of Congress’s outstanding, lawful requests for information — in the Ukraine matter and in other investigations — and if Trump does not comply, Congress has no choice but to impeach.”
Several other presidential candidates, including Senators Elizabeth Warren and Kamala Harris, have already called for impeachment. Ms. Warren has been particularly forceful, accusing Congress of shirking its constitutional responsibilities.
“After the Mueller report, Congress had a duty to begin impeachment,” Ms. Warren tweeted on Friday. “By failing to act, Congress is complicit in Trump’s latest attempt to solicit foreign interference to aid him in US elections. Do your constitutional duty and impeach the president.”
In the House, the recent reports that Mr. Trump pressured Ukraine’s president to investigate Mr. Biden, shortly after he froze American aid to Ukraine, has led many previously reluctant Democrats to support impeachment proceedings. A series of moderate lawmakers, including freshmen from swing districts, have gotten on board this week, and Speaker Nancy Pelosi will meet Tuesday afternoon with committee leaders who have led investigations of the president.
At the United Nations on Tuesday morning, Mr. Trump said he had held up the aid because other European countries had not paid enough to support Ukraine. He released the aid under pressure from Congress after the delay was publicly reported.
