Last October, at a library in Boynton Beach, Fla., Yelyzaveta Demydenko went with her mom and stepdad to vote for the first time.

Demydenko, who’s 22, told a federal investigator that she voted in the presidential election “because she wanted to make a difference.” Her mother, Svitlana, also voting for the first time, said she cast a ballot “because she wanted to support the country.”

The women, who were born in Ukraine, are green card holders, not U.S. citizens, as is required to vote in federal elections. They now represent two of the first illegal voting charges brought by the Justice Department under President Trump.

The same week, federal law enforcement also announced charges against an Iraqi man accused of casting a ballot in the 2020 election, and a Jamaican woman accused of illegally voting in last year’s presidential primary in Florida.

The four cases were made public about a month after Trump signed an executive order that seeks to add new document checks to voter registration, and as Republicans in Congress and in legislatures across the country try to pass laws with similar restrictions.
