A Florida woman was charged on Thursday after officials said she filled out 10 voter registration forms with false information, at least six of which enrolled Democratic and independent voters in the Republican Party without their consent.

The woman, Cheryl A. Hall, 63, of Clermont, Fla., worked for Florida First, a voter registration group heavily funded by America First Policies, which supports President Trump.

America First Policies announced plans last year to spend more than $20 million on voter registration efforts in at least four battleground states: Florida, Georgia, North Carolina and Pennsylvania.

Alan Hays, the supervisor of elections in Lake County, Fla., near Orlando, said that although Ms. Hall was charged with submitting 10 false voter registration forms, he believes she might have submitted another 109 forms with false information.
