Former U.S. Ambassador Bill Hagerty officially launched his bid for U.S. Senate Monday, confirming a campaign that he'd been keeping quiet about despite President Donald Trump's announcing it for him in a tweet in July.

Hagerty, a longtime ally of Utah Sen. Mitt Romney and Tennessee's economic and community development commissioner under Gov. Bill Haslam, immediately moved to nationalize the race.

The open U.S. Senate race in Tennessee just got interesting.

Former Gov. Bill Haslam decided he will not run, opening the door for other Republicans who may have been holding back. And the next day, President Donald Trump tweeted that the U.S. ambassador to Japan, Tennessee's Bill Hagerty, is getting into the race.
