Dan Bongino snagged a big endorsement Monday, just one day before the Republican primary.

Sen. Ted Cruz announced Monday he was backing Bongino in Florida’s 19th Congressional District. In a statement, the Texas Republican and one-time presidential hopeful said there was “no doubt” in his mind that Bongino would defend the Constitution.

“Dan spent his life in public service, first as a police officer, and then as an agent in the United States Secret Service,” said Cruz in a statement on Facebook. “There’s no doubt in my mind that in our nation’s capital Dan would be a relentless advocate for and defender of our Constitution — just as he has been his entire life.”

The endorsement comes one day before the primary. Bongino faces Chauncey Goss and Francis Rooney in the Republican primary. The winner will face Democrat Robert Neeld in November.
