Yeah Trump really answers the hard questions... not. He meanders and he's vague or he simply lies. Here's how he answered regarding losing the election in 2020.
Asked for proof to back up his false claims that the 2020 presidential was stolen from him by mass voter fraud, Trump told Rogan:

“We’ll do it another time.

“I would bring in papers that you would not believe, so many different papers. That election was so crooked, it was the most crooked.”

Rogan pressed him for evidence.

Trump alleged irregularities with the ballots in Wisconsin and that Democrats “used Covid to cheat”.

“Are you going to present this [proof] ever?” asked Rogan.

“Uh…,” said Trump before pivoting to talk about how 51 former intelligence agents aligned with Joe Biden had falsely suggested that stories about his son Hunter Biden’s laptop were Russian disinformation.

“I lost by, like, I didn’t lose,” said Trump, quickly correcting himself.

Typical Trump.
