Two armed Virginia men who were arrested Thursday outside the Philadelphia Convention Center were “coming to deliver a truck full of fake ballots” to the city, CNN affiliate KYW reported, citing prosecutors.

The center is one of the places where election workers have been counting votes from the 2020 general election, which includes the race for president.

Text messages reveal that the men were concerned about the tallying of votes at the convention center, prosecutors said, according to KYW.

Antonio LaMotta, 61, and Joshua Macias, 42, both of Chesapeake, Virginia, were arrested Thursday night outside the center on suspicion of carrying handguns in Pennsylvania without permits, authorities said.
