Ted Cruz (R-TX) at a rally in Houston, TX on Monday night.
Because of course who could forget the 2016 election's connection to the John F. Kennedy assassination by way of the National Enquirer?
"I think they wanted to see that I'm on his side, and I am, 100 percent", Trump said when asked about why he was heading to Texas.
Cruz, for his part, has called Trump a "snivelling coward" and a "pathological liar".
The rally comes on the same day as early voting kicks off in Texas.
More than 7,000 people headed for United States in migrant caravan
Hundreds of locals driving pickups, vans and cargo trucks stopped to let them clamber aboard. He said the migrants' rights must be protected as they break into Mexico and head north.
Trump promised he would come to Texas after the Senate race grew closer than expected, with O'Rourke out-fundraising Cruz and drawing large and enthusiastic crowds around the state.
Although political relationships tend to be fluid, Trump's appearance for Cruz is notable, given that the two were bitter enemies during the 2016 primaries.
In a boost to Republicans ahead of the midterm elections next month, Trump is stumping for Sen. "Very late into the campaign and I said don't worry about it, it's only a question of time, and then it became very nasty and then it was over and, when it was over, we got along great".
"I don't know that Texans care too much one way or another what someone from outside of Texas thinks", O'Rourke said. The two were the last men standing in the 2016 GOP presidential primary and Cruz famously declined to endorse him at the Republican convention.
"I like him a lot". "This is a decision that will be decided by and for the people of Texas, and I feel really confident in that".
