House Speaker Nancy Pelosi on Thursday ratcheted up pressure on lawmakers to impeach Donald Trump, accusing the president of attempting to bribe Ukraine’s leaders to investigate Trump’s political rival Joe Biden and his son. 

Speaker Nancy Pelosi: “The bribe is to grant or withhold military assistance in return for a public statement of a fake investigation into the elections. That’s bribery. Yes.”

Bribery is specifically mentioned as an impeachable offense in the U.S. Constitution.
