The Department of Justice on Friday announced that 19 foreign nationals have been charged with voting illegally in the 2016 presidential election.

Of the 19, nine made false claims of U.S. citizenship in order to vote, according to the charging documents.

Immigration and Customs Enforcement is said to be taking the lead in investigating the cases.

Conviction for a false claim of U.S. citizenship in order to register to vote and voting by an alien carries a maximum penalty of six years in prison, a $350,000 fine and a term of supervised release following any imprisonment.

President Trump in 2016 claimed, without evidence, that millions of illegal ballots were cast for Democratic presidential nominee Hillary Clinton and that without them he would have won the popular vote.

In addition to winning the Electoral College in a landslide, I won the popular vote if you deduct the millions of people who voted illegally
