"Like many other voters, I'm watching and listening and assessing what he says and what he does, and I think that's what millions of voters are doing and that's the way the democratic process is meant to operate," Cruz said, according to MSNBC.

"I think voters are going to do that from now right until Election Day, and I'm giving it time and watching and assessing."

Cruz, who dropped his presidential bid last month, feuded with Trump, now the presumptive GOP nominee, several times during his campaign. Before dropping out of the race, Cruz called Trump an "utterly amoral" pathological liar, narcissist and bully.

Last month, the Texas senator told reporters he had plenty of time to make a decision on whether or not to back Trump.

Cruz told MSNBC that he is focused on "defending conservative principles," noting he thinks the party's platform should reflect those principles.

"I am fighting for those principles now in the United States Senate. I had hoped to fight for them and implement those principles from the White House," he said.

"It turned out that was not the way the election went and so I'm back here in the Senate working hard to fight for those very same principles."

He said the American people are looking for a leader who will "get Washington off of our backs, that will bring back jobs and economic growth, that will defend the Constitution and that will keep this country safe."

"And I hope that's what we end up with," Cruz said.

Trump has come under fire over comments he made questioning whether an Indiana-born federal judge might be biased against him because of his Mexican heritage. Republican leaders have condemned Trump's remarks.
