Washington (CNN) President Donald Trump said Tuesday that he's spoken with Sen. Cindy Hyde-Smith about her comments referencing a "public hanging" and suggested her apology should suffice.

"I know her. And I know she apologized. And she misspoke," Trump told reporters on the South Lawn as he left to hold a pair of rallies supporting Hyde-Smith in Mississippi.

"I've known her for a period of time now as a senator," he said. "She's been an excellent senator. She's done a great job. She's somebody that's respected in the Senate."

Hyde-Smith joked about going "front row" to a "public hanging" in a video posted to Twitter earlier this month, prompting her African-American opponent to call her comment "reprehensible." She faces former Democratic Rep. Mike Espy in a runoff election on Tuesday.

"If he invited me to a public hanging, I'd be on the front row," Hyde-Smith is heard saying in the video.
