Former Massachusetts Gov. Bill Weld said Friday he is thinking about challenging President Trump for the 2020 Republican presidential nomination.
Weld, a moderate Republican, was twice elected governor. He supports abortion rights and was an early proponent of gay rights.
He resigned his post as governor after being offered the ambassadorship to Mexico, but the nomination stalled in the Senate after opposition from other Republicans.
Weld then ran as the Libertarian Party's vice presidential nominee in 2016 on a ticket with former New Mexico Gov. Gary Johnson.
According to The Washington Post, Weld told the Politics & Eggs breakfast in Bedford, N.H., on Friday that Trump "acts like a schoolyard bully" and that Republicans in Washington who support him "exhibit all the symptoms of Stockholm syndrome."
"We don't need six more years of the antics we have seen," Weld said.
Weld faces an uphill battle in taking on Trump, who remains popular with Republican voters. He also isn't the only Republican who has mused about challenging the president.
But a primary challenge, even if unsuccessful, could conceivably weaken Trump, as past primary challenges hurt George H.W. Bush and Gerald Ford, both of whom fought primary opponents before losing the general election for another term.
