President Obama brushed aside House GOP plans to file suit over his use of executive actions to bypass Congress, calling the legal action a “stunt” and vowing not to let him stop him from taking more executive actions in the future.

“I'm not going to apologize for trying to do something while they're doing nothing,” Obama told ABC News' George Stephanopoulos during an interview Thursday in Minnesota.

“This suit is a stunt,” he later added.

Later during an address on the economy in Minnesota, Obama dismissed Republicans as ineffective bullies.

"They don't do anything except except block me and call me names," he told the crowd.

White House press secretary Josh Earnest earlier this week said the lawsuit would have no impact on Obama's plans or thinking regarding issuing future executive orders.

Republicans are bracing for a second immigration-related executive order from Obama this fall and hope the lawsuit might have a deterrent effect. Senior White House officials have said House Republicans have a window of opportunity -- until the end of the summer -- to act on immigration reform.

Obama issued an executive action in June of 2012 to hundreds of thousands of illegal immigrants who came to the United States before the age of 16 to remain in the country and to work legally and obtain driver's licenses and other legal documents.

Many Republicans believe that order helped create the current crisis at Texas' southern border by obscuring the nation's laws regarding children immigrants.

The Supreme Court this week unanimously rebuked Obama on his right to appoint federal officials during a Congressional recess, arguing that he had overreached in making the appointments during breaks in the Senate's work schedule.

Pushing back against Obama's remark that the House GOP lawsuit is a “stunt,” Rep, John Boehner's spokesman Michael Steel said Republican leaders are trying to respond to public outrage over what some view as presidential overreach.

“The American people, their elected representatives and the Supreme Court have all expressed serious concerns about the President’s failure to follow the Constitution,” Steel said. “Dismissing them with words like, ‘smidgen’ or ‘stunt’ only reinforces their frustration.”

Sen. John Cornyn, R-Texas, took it a step further, accusing Obama of doubling down on his efforts “to govern by fiat.”
