"Congratulations to my friend @harrisonjaime on officially launching his campaign to unseat Lindsey Graham in SC," Buttigieg, the mayor of South Bend, Ind., tweeted. "He will make a great Senator—and a positive change."

Harrison announced Wednesday that he would challenge Graham for his seat in 2020.

"Lindsey Graham can’t lead us in any direction, because he traded his moral compass for petty political gain,” Harrison said in an announcement video.

“I remember a time when senators helped the people they represented,” he added. “I want to bring the spirit of helping back, and that’s why I am running for the United States Senate.”

Harrison and Buttigieg both ran unsuccessfully for the Democratic National Committee chairman post in 2017.

Buttigieg is among two dozen people vying for the Democratic Party's 2020 presidential nomination.
