The communications director for Rep. Lauren Boebert of Colorado, a firebrand Republican freshman who boasts about carrying a gun to work, has quit after less than two weeks on the job.Why it matters: Ben Goldey’s resignation cited last week's insurrection at the U.S. Capitol, which followed efforts by Boebert and lawmakers to block certification of Joe Biden’s Electoral College victory. The Hill veteran’s departure highlights the deep divide among Republicans over President Trump’s conduct.Get smarter, faster with the news CEOs, entrepreneurs and top politicians read.

I wish her and the people of Colorado’s Third District the best."Between the lines: Boebert is a strident Trump supporter firmly on the right flank of the House GOP caucus. She was clear about her views during her campaign, but they have suddenly become politically toxic following last week's attack. * Boebert’s quickly become a lightning rod by railing against “fraudulent” votes for Biden in a floor speech ahead of the attack, and by making a show — including in an ad filmed on the Hill — of her desire to carry a handgun in the Capitol. * Goldey, by contrast, has a more establishment pedigree. He was the press secretary at the Department of Interior until this year, and previously worked for Senate Majority Leader Mitch McConnell.Be smart: Goldey’s resignation underscores larger Republican divisions, particularly in the House, where ten GOP members - including conference chair Rep. Liz Cheney - voted to impeach Trump on Wednesday. * The same divisions are evident on the other side of the Capitol. Sen. Ted Cruz's communications director, Lauren Blair Bianchi, also resigned on Monday, reportedly over Cruz's role in the effort to deny certification for Biden. * Trump has fueled the split since the election, demanding the president-elect’s win be overturned, helping incite the violence at the Capitol last week and remaining defiant about his behavior even as he faced his second impeachment by the House yesterday.Be smart: sign up FREE for the most influential newsletter in America.
