BBC- The US House of Representatives will vote on Wednesday on sending articles of impeachment against President Donald Trump to the Senate, Democrats say.
House Speaker Nancy Pelosi told fellow Democrats she would also name the House managers who will prosecute the case against Mr Trump in the Senate trial.
Mrs Pelosi has been withholding the articles of impeachment in a row with Republicans over allowing witnesses.
Mr Trump was impeached by the Democratic-led House last month.
He is accused of abuse of power and obstruction of Congress.
He denies trying to pressure Ukraine to open an investigation into his would-be Democratic White House challenger Joe Biden.
Mr Trump has been touting unsubstantiated corruption claims about Mr Biden and his son, Hunter, who accepted a lucrative board position with a Ukrainian energy firm while his father handled American-Ukraine relations as US vice-president.
The impeachment trial by the Senate will be only the third ever of a US president.
Mr Trump’s fellow Republicans control the chamber 53-47, and are all but certain to acquit him.
