Republican Representative Kelly Armstrong on Thursday introduced a 14-page resolution that would allow the House to vote on authorizing the investigation

The Republican-controlled U.S. House of Representatives is expected to vote on Wednesday to formalize an impeachment investigation into Democratic President Joe Biden.

Reuters reports. 

It is noted that official plans for the vote remain unclear. Earlier on Monday, a Republican lawmaker said that House Speaker Mike Johnson had revealed plans to vote on Thursday in a closed session, a timeframe echoed by other Republicans.

On Thursday, the House of Representatives is set to leave Washington for a more than three-week end-of-year recess.

House Republicans accuse the Democratic president and his family of unduly benefiting from policy decisions Biden took part in as vice president during the 2009-2017 administration of President Barack Obama.

They also accuse the U.S. Department of Justice of improperly interfering in the investigation of Biden's son, businessman Hunter Biden. The Justice Department denies any wrongdoing.

On Thursday, Republican Representative Kelly Armstrong introduced a 14-page resolution that would allow the House of Representatives to vote to authorize the investigation.

So far, House Republicans have been unable to provide evidence linking Biden's actions as vice president to his son's business, and it is unlikely that the Senate, where Biden's Democratic Party has a slim majority, will vote to convict the president if the House passes impeachment articles.

Representative Byron Donalds, a Republican member of one of the three committees investigating Biden, told Fox News on Sunday that he expects the investigation to wrap up within the next two months and the House to draft articles of impeachment sometime in the spring.
