THE US House of Representatives has voted to formalise its impeachment inquiry into President Joe Biden.
Lawmakers voted along party lines to back a resolution that Republicans say will give them more power to gather evidence and enforce legal demands.
Three Republican-led House committees allege bribery and corruption during Mr Biden’s tenure as vice-president.
But they have yet to present evidence of wrongdoing, and Mr Biden says his opponents are “attacking me with lies”.
The lower chamber of Congress, which Republicans control by a slim eight-seat margin, approved the inquiry on Wednesday afternoon by a vote of 221 to 212.
Voting to authorise an inquiry is not the same as voting for impeachment, but it advances the likelihood that the House will eventually seek to impeach Mr Biden.
In a statement, House Speaker Mike Johnson said the chamber “will not prejudge the investigation’s outcome” but “the evidentiary record is impossible to ignore”.
A formal impeachment investigation, that leads to a House vote and a Senate trial, could represent a major headache for the president in the midst of an election year.
But, even if the House ultimately opts to impeach the president, the Democrat-controlled Senate is all but certain to acquit him.
“The American people need their leaders in Congress to take action on important priorities for the nation and world,” Mr Biden said in a statement following the vote.
“Instead of doing their job on the urgent work that needs to be done, they are choosing to waste time on this baseless political stunt that even Republicans in Congress admit is not supported by facts.”
In an animated debate ahead of the vote, Oklahoma Republican Tom Cole said his colleagues had been left with no choice but to bring the measure.
He said it was a “sad day for myself, the institution and the American people” and accused the White House of “stonewalling” the impeachment inquiry.
But Democrats expressed irritation over what they have dismissed as “an extreme political stunt”.
Jamie Raskin of Maryland said the investigation “isn’t a whodunit, it’s a what is it”.
“It’s like an Agatha Christie novel, where the mystery is – what’s the crime?” he added.
