President-elect Donald Trump is meeting Saturday with Mitt Romney to purportedly discuss the possibility of Romney becoming secretary of state.

Trump and Romney, a former GOP presidential nominee, are meeting at Trump’s golf club in Bedminster, N.J.

Romney was one of Trump’s most outspoken Republican critics during the 2016 primary season. The meeting Saturday is one of several Trump has been holding with prominent Republicans to fill Cabinet-level posts, after Trump’s upset White House win on Nov. 8.

The Trump-Romney meeting could at least be a chance for the two to set aside their differences from the 2016 season and forge political unity.

Trump and Romney viciously attacked one another during the primaries. Though Trump had endorsed Romney in 2012, he repeatedly mocked his campaign performance against President Obama, calling him “the biggest loser” and “weak.”

Romney refused to support Trump, instead focusing his resources on down-ballot races like Ohio Sen. Rob Portman.

Romney called Trump a “fraud” in a speech he delivered in March in which he asked Republicans to vote for Florida Sen. Marco Rubio, Ohio Gov. John Kasich or Texas Sen. Ted Cruz.

“One of these men should be our nominee,” he said.
