Transportation Secretary Pete Buttigieg thinks former President Donald Trump is likely not looking forward to a future presidential debate against Vice President Kamala Harris .

During an appearance on CNN s The Source on Tuesday, Buttigieg told anchor Kaitlan Collins that he believes Trump is afraid to debate Harris because shes going to be so effective, and shes going to lay bare his inability to talk about anything but himself and his past.

When Collins noted that Trump had said on Tuesday that he would absolutely debate Harris , Buttigieg pointed out the timing of Trumps initial complaints about the debate.

The Trump campaign had previously agreed to two presidential debates leading up to the November election. The first debate was held on June 27, and the second is set for Sept. 10, with ABC News hosting.

But hours after Biden dropped his bid for reelection and endorsed Harris as the new Democratic nominee shortly afterward on Sunday, Trump took to Truth Social to complain that his campaign has had to start all over with the time and money it spent fighting Biden. He also called for the debate to be held on Fox News instead.

Now that Joe has, not surprisingly, has quit the race, I think the Debate, with whomever the Radical Left Democrats choose, should be held on FoxNews, rather than very biased ABC, Trump wrote.
