Republican presidential candidate Marco Rubio told a Kentucky Sports Radio host he does not regret his petty attacks about the size of Donald Trump’s hands, but added if he did have regrets, it would be “because Jesus would be embarrassed about it.”

Rubio’s quip about Trump’s hands led to a crass remark from Trump during Thursday night’s debate when the Republican front-runner defended his sexual prowess on live television.

Rubio spoke to Kentucky Sports Radio, the state’s largest sports talk show, one day before Kentucky Republicans cast votes in the first presidential caucus since 1984.

Rubio told host Matt Jones that Kentuckians’ votes matter and that he believes politics will never be the same after this election cycle. He said Trump has dangerously divided the Republican party.
