President Donald Trump is now publicly patting himself on the back for endorsing state Rep. Katie Arrington ahead of her win over U.S. Rep. Mark Sanford in Tuesday's S.C. Republican primary.

In a tweet Wednesday morning, Trump said he went against the instincts of his advisers and chose to dive into South Carolina GOP politics.

"My political representatives didn't want me to get involved in the Mark Sanford primary thinking that Sanford would easily win - but with a few hours left I felt that Katie was such a good candidate, and Sanford was so bad, I had to give it a shot," Trump wrote.

"Congrats to Katie Arrington!," he also boasted.

Trump endorsed Arrington in a tweet delivered three hours before the polls closed Tuesday.

His message Tuesday called Sanford "nothing but trouble" and said the former South Carolina governor should return to Argentina, site of his 2009 trip to visit his mistress when he was governor.

"Mark Sanford has been very unhelpful to me in my campaign to MAGA. He is MIA and nothing but trouble. He is better off in Argentina. I fully endorse Katie Arrington for Congress in SC, a state I love. She is tough on crime and will continue our fight to lower taxes. VOTE Katie!" he said.

Sanford has been one of the few lawmakers to publicly criticize Trump's behavior in the months leading up to Tuesday.
