California Rep. Eric Swalwell is vowing to aggressively push back on federal immigration officers if elected governor. The Democrat says he would use the office to make federal agents ineligible for state jobs and take away their driver’s licenses if they refuse to unmask while on duties. He hasn't specified how he’d advance those policies. Swalwell is among a crowded field jostling to replace Gov. Gavin Newsom who terms out after this year. Swalwell says he has a proven record of fighting Trump. Mail-in ballots begin going out next month ahead of the June 2 primary.
