President Donald Trump has encouraged a retired Navy SEAL to challenge Republican Rep. Thomas Massie in next year’s Kentucky primary. Trump built up his choice last week as “A WINNER WHO WILL NOT LET YOU DOWN.” It came in the Republican president's latest social media barrage against a congressman who has crossed him on high-profile issues. Trump’s choice, Ed Gallrein, has not entered the 4th District campaign but says he'll reveal his plans soon. Gallrein is a farmer and businessman who had a long military career and last year ran for a state Senate seat, narrowly losing in the Republican primary.
