Scenes from President Donald Trump's Rally for U.S. Senator Ted Cruz

President Donald Trump rallied support for his onetime foe Sen.

Cruz, speaking before Trump, hailed the president as "a man who has presided over record jobs, record unemployment" and said he looks forward to hitting the campaign trail for his reelection campaign.

U.S. Sen. Ted Cruz (R-TX) debates U.S. Rep. Beto O'Rourke (D-TX) at the KENS 5 studios on October 16, 2018 in San Antonio, Texas. "I'm a nationalist", Trump said to cheers of the crowd.

The president acknowledged his rocky relationship with Cruz when they were fierce competitors in the 2016 GOP presidential primary.

CNN anchor Don Lemon expressed his shock from what he called a "surprisingly candid admission" from President Donald Trump.

Despite O'Rourke's national buzz as a progressive liberal over-performing in the conservative bastion of Texas, he still trails in most polls by almost ten points.

The president took to the stage alongside senator Ted Cruz Monday, where the two touted the success of republican policies and how they've benefited the American people.

President Trump said Tuesday that he does think of himself as a "nationalist" in in that he's a patriot who's exhausted of seeing foreign nations take advantage of America. He called O'Rourke "far too liberal for Texas". The event was shifted to a larger arena to accommodate interest, according to Mr. Trump's campaign. "And then it ended and I'll tell you what nobody has helped me more". I actually like him a lot, and he's a very smart guy.

Cruz, for his part, has called Trump a "sniveling coward" and a "pathological liar". The last time the Democratic party won a statewide race was 1994; Cruz's seat should be safe.

The race in Texas is likely to be costing Trump some sleep.

"I think now he's going into the midterms, he understands that the base that got him elected in 2016 is still the base he needs now and that is predominantly white, predominantly male and non-college educated and he's doing racist dog whistles to appeal to them", he concluded. Cruz remains ahead in the polls by several points.

Trump is well aware of the power he has to energise people.

He said he was referring to wealth the United States passes on to countries that "don't treat us properly" through trade deals and security organizations.

It was a packed house at the Toyota Center in Houston where Trump praised the Texas senator for working closely with him on tax cuts and regulations.
