President Joe Biden laughed off a question about whom he wants to win the 2024 Republican presidential nomination while speaking to reporters on Tuesday.

Biden took one question before departing the White House for a three-day campaign trip to California but declined to say if he would rather run against former President Donald Trump, the likely Republican nominee, or former U.S. Ambassador to the United Nations Nikki Haley, who is hoping to pull off a last-minute coup of Trump in her home state of South Carolina in Saturday’s primary.
