Rep. Jim Clyburn (D-SC) was President Joe Biden‘s key to winning the Democratic nomination in 2020, but as the president has faced mounting calls to step aside from the 2024 campaign, the influential South Carolina Democrat has offered a variety of statements.

Clyburn was scheduled to appear on CBS News’s Face the Nation on Sunday, but his staff informed the show on Friday that he would have to cancel his appearance, according to the network. The appearance would have capped off a week of statements from the longtime congressman about the future of Biden’s candidacy that created headlines.
