O'Rourke on Cruz: "We were both elected in the same year, we both have young children. I know how hard he works, what a sacrifice it is to his family. ... He wants to serve this country. ... We have differences of opinions on the destinations, but no question he wants to do what's best for America."

Cruz on O'Rourke: "Being a dad with young kids is hard, I know the sacrifice you’re putting in. ... Beyond that, I think Congressman O’Rourke is passionate and energetic and believes in what he’s fighting for."

Cruz, O'Rourke tussle over police shootings

7:55 p.m.

Cruz yet again took aim at O'Rourke over his response that a Dallas police officer, who fatally shot an unarmed man in his own apartment, should be fired. He took aim at O’Rourke for what he says is jumping to conclusions.

"It’s a troubling pattern," Cruz said. "He sides against the police."

O’Rourke later lashed out at Cruz for what he described as scare tactics.

“That’s why people don’t like Washington, D.C.,” O’Rourke said. “This is your trick and trade, to confuse and incite with fear.”

Clash over 'thoughts and prayers'

7:45 p.m.

When discussing guns and school safety, O'Rourke said that "thoughts and prayers are not enough."

Cruz shot back: "I'm sorry that you don't like thoughts and prayers, I'll pray for anyone in harm's way" and then work to make schools safer.

O'Rourke addresses past drunk driving arrest

7:37 p.m.

O'Rourke was asked about a recent report that he tried to leave the scene in his past 1998 arrest for drunk driving. O'Rourke denied that.

"I did not try to leave the scene of the accident," O'Rourke said. "Driving drunk, which I did, was a terrible mistake."

The congressman also used his response to talk about his "privilege" as a white man and talked about how African-Americans who face arrests should also get a "second chance."

Cruz puts the past behind him on Trump

7:34 p.m.

A debate moderator pressed Cruz about his contentious relationship with President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?' Romney: 'Unthinkable and unacceptable' to not commit to peaceful transition of power Two Louisville police officers shot amid Breonna Taylor grand jury protests MORE during the 2016 GOP presidential primary but his vocal support for him now.

Cruz said there were some “hard shots thrown” in the GOP primary, but that he made a deliberate choice to work with the president.

"I could have chosen to make it about myself," Cruz said. "I think that would have been not doing the job I was elected to do."

Cruz also took a swipe at O'Rourke, claiming he'd vote to impeach Trump over the July summit in Helsinki between Trump and Russian President Vladimir Putin, which stoked backlash over Trump's handling of the meeting.

"The moderate Democratic Party is consumed with hatred for Donald Trump," Cruz said.

7:25 p.m.

Cruz invoked a familiar GOP boogeyman — Hillary Clinton.

The Republican senator said O'Rourke was against Supreme Court nominee Brett Kavanaugh even before sexual misconduct allegations were levied against him, saying that O'Rourke is siding with Clinton and liberal activists on judges.

O'Rourke said that he doesn't think Kavanaugh is fit to serve on the bench, pointing to his "troubling history" on voting rights protections.

Cruz said he wants both Kavanaugh and his accuser, Christine Blasey Ford, to testify before the Senate.

O'Rourke said he wants the FBI to investigate the allegations: "full stop."

Immigration becomes heated flashpoint

7:15 p.m.

Cruz, who called for building a border wall, accused O'Rourke of being "out of step with Texas" on the issue of immigration.

"His focus seems to be fighting for illegal immigrants," Cruz said. "Americans are dreamers too."

O'Rourke said that he believes there should be an "earned path to citizenship" for "Dreamers," immigrants who came to the country illegally as children.

"The alternative, as Sen. Cruz has proposed, is to deport 11 million people from this country," O'Rourke said.
