Iowa Secretary of State Matt Schultz says his efforts to prevent election irregularities did not suppress the vote in the November election.
Schultz told the U.S. Senate Judiciary Committee on Wednesday that Iowa had a record turnout in the election, which shows his "election integrity efforts" did not deter legal voters as some critics had claimed.
Schultz testified during a hearing examining voting problems in the election, which included long lines in Florida and elsewhere.
The first-term Republican has been a lightning rod of criticism for taking steps to find and prosecute possibly ineligible voters. He led an unsuccessful effort to check the citizenship of voters who may have been noncitizens. And he hired a state criminal investigator to probe potential misconduct, resulting in charges against 8 individuals so far.
