The Department of Homeland Security is investigating 1,620 cases of alleged voter fraud involving noncitizens and reviewing hundreds of thousands of additional cases, DHS Secretary Markwayne Mullin said.

Mullin told Fox News that DHS has made 151 arrests and is examining another 300,000 cases based on information compiled from state voter rolls.

"We're scrubbing them. We're comparing them to those that are in the country illegally, those that are legal permanent residents and those that are citizens" to determine whether they voted legally, Mullin told Fox News contributor Kayleigh McEnany.

The investigation puts renewed attention on election integrity and the participation of noncitizens in U.S. elections, an issue President Donald Trump has repeatedly raised.

According to Mullin, the cases uncovered by DHS support Trump's longstanding contention that election fraud has occurred.

"We continue to see that. Every single vote, Kayleigh, that we talk about, that was at the hands of an illegal canceled out a citizen that was legally registered and able to vote," Mullin said.

DHS is examining the additional cases to determine whether individuals identified on state voter rolls were citizens, legal permanent residents or in the country illegally, according to Mullin.
