WASHINGTON (Reuters) – Former President Donald Trump has endorsed challengers to five congressional Republicans, part of his effort to assert dominance over the party after losing his November re-election bid to Democrat Joe Biden.

Trump is focusing his anger on the small number of Republican lawmakers that voted to impeach him for inciting the Jan. 6 U.S. Capitol firestorm or convict him in a Senate court that ended in his acquittal.

Below are notable Republicans that Trump aims to take down through his endorsements

REPRESENTATIVE ANTHONY GONZALEZ

Gonzalez, a two-term U.S. representative from Ohio who voted to impeach Trump for inciting supporters to launch a deadly assault on the Capitol, on Thursday became the first of Trump’s targets to withdraw https://www.reuters.com/world/us/republican-congressman-who-voted-impeach-trump-wont-seek-re-election-2021-09-17 from a re-election bid after the former president endorsed a Republican challenger.

The Ohio Republican Party had rebuked Gonzalez for voting against impeachment. They called him to resign from his congressional seat. Gonzalez stated that “the toxic dynamics within our party” were responsible for his decision to withdraw. Trump has supported Max Miller, a former White House adviser for Gonzalez’s seat.

REPRESENTATIVE LIZ CHENEY

REPRESENTATIVE FRED UPTON

Upton, who has represented Michigan in the House since 1987, was an early critic of Trump’s false claims that he lost the November presidential election due to widespread fraud.
