From a Diane Black campaign email blast earlier today:

"...there’s STILL a deafening silence coming from Diane’s 3 Republican gubernatorial challengers – Randy Boyd, Bill Lee and Beth Harwell – who are part of, and beholden to, the moderate establishment that supports Phil Bredesen. Boyd, who’s supported multiple Democrats throughout his career, implied that he couldn’t endorse Blackburn because Rolondo Toyos was still in the race. But over the weekend, the TNGOP removed Dr. Toyos from the ballot. What excuse will Boyd come up with next?"

Randy Boyd tweet, shortly thereafter:

"With a clear field, proud to officially endorse & support Marsha Blackburn for the U.S. Senate. She’s been a great Congressman & will be a great Senator! Looking forward to working with her on a big GOP victory all across TN this fall!"
