Buzzfeed News reported that Sen. Mike Lee (R-UT) will endorse Sen. Ted Cruz (R-TX) on Thursday afternoon, citing two anonymous sources with knowledge of Lee’s plans.
Politico also reported that Lee will endorse Cruz in Florida on Thursday.
Lee would be the first senator to endorse Cruz’s presidential bid. The Utah senator has been closely aligned with Cruz and helped him orchestrate the 2013 federal government shutdown.
On Monday, the National Review reported that four senators would announce their endorsements of Cruz but later corrected the report.
