A campaign aide to Donald Trump called for conservative commentator Hugh Hewitt to be banned from the Republican National Convention after he said the GOP should change its rules in order to block Trump from winning the presidential nomination.

{mosads}Dan Scavino, the Trump campaign’s social media director, tweeted on Wednesday that “the RNC should BAN him from attending” the convention.

Assume hater Hugh Hewitt will not be attending the @GOP Convention. If he is – the RNC should BAN him from attending.

Earlier on Wednesday, Hewitt said suggesting the party should free delegates to decide on a nominee.

“I want to support the nominee of the party, but I think the party ought to change the nominee, because we’re going to get killed with this nominee,” he said on his radio show. “They ought to get together and let the convention decide.”
