When MSNBC's Chris Matthews needed someone to put on "Hardball" Monday night to counter a Donald Trump adviser, he picked Miami Mayor Tomás Regalado.
Regalado went on the cable news show in part to talk about police shootings. He touted his city's move to teach officers about "diversity and de-escalation" to reduce the number of killings by cops.
But then Matthews asked Regalado, a Republican in a non-partisan post, about Trump's potential running mate.
"Well, I think it doesn't matter to me, because I'm not supporting Trump," said Regalado, who has said he's not voting for Trump or for Democrat Hillary Clinton. "And the reason I'm not supporting [him] is because I don't think he's a candidate of compassion. A person with compassion does not call people that don't look like him murderers and drug dealers and rapists."
And Regalado kept going. He said he doubts Trump has a project for "law and order," as the presumptive presidential nominee has claimed.
"For the first time, Chris, in 20 years of being elected -- first as the commissioner as six years as a mayor -- I have been getting emails of people telling me, 'Go back to your country,'" said Regalado, who was born in Cuba. "This has never happened to me."
Regalado was cut off by Kellyanne Conway, a pollster and senior Trump adviser.
"Do you think it was compassionate to cut benefits for the police, mayor?" she said. "A couple of years ago, you cut benefits for the police."
Regalado acknowledged past cuts to the police -- and to himself and other city departments -- while the city was in a financial crunch.
But now, he said, "We're taking care of the police department."
