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.
In an official launch video posted online, he said he felt called to act against what he describes as a "threat to Tennessee and to our country by the Democrats' socialist agenda."
