Cruz and Trump were bitter rivals in the final stretch of the primary campaign. The Texas senator’s announcement of support, made on Facebook, comes just days before the first debate between Trump and Hillary Clinton. After Cruz snubbed Trump at the Republican convention in July by declining to outright endorse him during his remarks, Trump blasted Cruz on the way out, saying he didn’t even want his endorsement. After Trump retweeted an unflattering picture of Cruz's wife Heidi, Cruz called Trump a "sniveling coward." Cruz also praised Trump for releasing an updated list of potential Supreme Court nominees that includes Sen. Mike Lee.
