House Democrats believe a newly released transcript of President Trump’s call with Ukrainian President Volodymyr Zelensky proves their claim that he abused his office to try to find dirt on his chief political rival, Joe Biden.

“Donald Trump clearly pressured the Ukraine president to commence an investigation into the Biden family to dig up political dirt in order to bolster the president’s electoral prospects in 2020,” House Democratic Caucus Chairman Hakeem Jeffries of New York said Wednesday. “That is textbook abuse of power, and the transcripts have become Exhibit A in that regard.”
