Republican Florida Sen. Marco Rubio said Saturday he is not concerned about mail-in voting in the 2020 election in his home state — an issue that President Donald Trump has frequently and falsely derided as a threat to election security.

“No, I’m not concerned about mail-in voting in Florida,” Rubio told reporters during the question and answer portion of a conference call run by the Trump campaign aimed at discrediting potential Joe Biden vice presidential pick Rep. Karen Bass.

Rubio declined to comment further.
