A crowd of diehard Republicans have loudly booed Donald Trump when his name was mentioned during a congressman’s concession speech.

Ralph Norman narrowly lost the South Carolina Senate primary election on Tuesday night (yesterday Australian time) to Darline Graham, who was endorsed by Trump.

“The president got involved. He has that right. That’s his prerogative,” Norman said during his speech.

The crowd started to jeer and boo at the mention of Trump.

“Y’all, his policies are good. I never understood why he got in this race,” Norman said.

Even though Trump endorsed Norman’s opponent, it is close to unprecedented for conservatives in the US to boo the mention of his name.
