Republicans on Tuesday boycotted a Democratic-led subcommittee hearing on Arizona’s controversial immigration bill.

Sen. John Cornyn (R-Texas), the ranking member of the subcommittee, called the hearing “election-year theater.” He said it would do nothing to further attempts at reforming the country’s immigration system.

“This is not an attempt at having a sincere hearing on the merits,” Cornyn said in a statement. “Unfortunately, the Democrat majority seems to have embraced President Obama’s ‘mañana’ approach to immigration reform.”
