Trump Jr. took to Twitter to denounce the Utah senator, claiming that he is “forever bitter that he will never be” president.

“He was too weak to beat the Democrats then so he’s joining them now,” the president’s son tweeted. “He’s now officially a member of the resistance & should be expelled from the @GOP.”

Trump Jr.’s tweet followed Romney’s announcement that he will vote to convict the president in the Senate impeachment trial.

The Utah senator and 2012 presidential candidate was the first Republican to break from his party and say he would vote to convict Trump on a single impeachment charge of abuse of power.

The House passed two articles of impeachment against Trump in December, accusing him of abuse of power in his dealings with Ukraine and obstruction of Congress in his handling of the impeachment probe itself.

The GOP-led Senate is expected to acquit him of the charges on Wednesday evening after Republicans voted last week to bring the trial to an end without additional witnesses or documentation, which had been demanded by Democrats.
