Former President Trump was fed up when he decided to abruptly end an interview with NPR. The former Republican president left the interview when NPR continued to press him on repeated claims of fraud in the 2020 election and whether those claims are what led to the Jan. 6 Capitol riot.

The Hill reports:

The network said it had tried to conduct an interview with Trump for six years, but the former president had declined until Tuesday evening. The interview was planned to last 15 minutes, it added. However, Trump reportedly ended it after nine minutes when he was pressed on his claims about the 2020 election and questioned about the Jan. 6 riot at the Capitol.

Throughout the interview, Trump reportedly pushed for his fellow Republicans to support his claims and views that the election in 2020 was rigged.

NPR said it asked Trump about a quote from his former lawyer, Rudy Giuliani, shortly after the election. “This is not a fraud case,” Giuliani told a judge at the time.

“It was too early to ask for fraud and to talk about fraud. Rudy said that, because of the fact it was very early with the — because that was obviously at a very, very — that was a long time ago. The things that have found out have more than bore out what people thought and what people felt and what people found,” Trump replied.

Trump has repeated the claim that widespread voter fraud shifted the 2020 election in Democrats’ favor. However, election experts have not been able to prove there were enough instances of fraudulent voting to shift the outcome in another direction.
