Election officials across the country have found almost no cases of voter fraud in the 2016 election, but Rep. Steve King (R-Iowa) is convinced that 2.4 million people voted illegally.

In an interview with MSNBC’s Hallie Jackson on Tuesday, King responded to President Donald Trump’s evidence-free claim that there were between 3 and 5 million illegal voters in the election ― an assertion that puzzled even some of Trump’s supporters.

Citing “sample data from certain counties,” King told Jackson he had done his own calculations and determined it was “plausible” that 2.4 million people could have voted illegally.

“I ... did an extrapolation calculation on how many illegals could have or could be voting in the United States,” King said, using an offensive term for undocumented immigrants. “The number I came up with off of that extrapolation was 2.4 million. So it’s plausible ― the number 3 million sounds like it’s a plausible number to me.”
