Former President Donald Trump’s supporters should be able to protest “peacefully” if Trump is arrested for his involvement in possibly paying hush money during his 2016 presidential campaign, Sen. Mark Kelly said Sunday.
Trump’s supporters, “have First Amendment rights, and they should be able to exercise those peacefully,” Kelly (D-Ariz.) said on CNN's "State of the Union." But law enforcement officials should be prepared to “make sure it doesn't rise to the level of violence,” he added.
Kelly pointed out that levying charges against the former president would be “unprecedented,” acknowledging that “there's certainly risks involved” in doing so. However, “we're a country of laws and nobody is above the law,” Kelly said.
“If they come to the conclusion that he should be charged, the former president has some constitutional rights, and this is a process that's going to need to be worked out between him and his lawyers,” Kelly said.
