Romney’s swearing-in comes days after he published an op-ed critical of President TrumpDonald John TrumpFlorida GOP lawmaker says he's 'thinking' about impeachment Democrats introduce 'THUG Act' to block funding for G-7 at Trump resort Kurdish group PKK pens open letter rebuking Trump's comparison to ISIS MORE, who he argued hasn’t “risen to the mantle” of the presidency. 

The op-ed earned him pushback from President Trump, members of his own family and some of his Republican colleagues.

It’s a U-turn for Romney, who had routinely brushed off questions from reporters as he shuffled around the U.S. Capitol attending freshman orientation and largely kept his public focus off Trump following his comfortable election win. 

Reporters tried to approach him as he headed into the Senate chamber but were brushed off by a handler.  

Romney is one of nine new senators sworn, eight of whom were sworn in on Thursday. Sen.-elect Rick Scott (R-Fla.) is expected to be sworn in later this month.
