Former President Donald Trump abruptly ended an interview with National Public Radio after the outlet questioned him on his repeated claims that the 2020 election was stolen from him by voter fraud.

The interview, which NPR teased as being “six years in the making,” was scheduled to go 15 minutes, but lasted just over nine as “Morning Edition” host Steve Inskeep pressed the former president on the election outcome. The interview was posted to NPR’s website Wednesday morning.

Inskeep highlighted comments from Sen. Mike Rounds (R-SD), who said over the weekend that Trump “simply did not win the election.”
