Louisiana Gov. Bobby Jindal (R), addressing the Conservative Political Action Conference Thursday, excoriated fellow Republicans in Congress for failing to do enough to repeal President Obama's health-care law or stop Obama's plan to delay deportations for some young undocumented immigrants.

 "He has basically broken the Constitution. Broken the law," Jindal said of Obama. "It is time for our Republican leaders in congress to grow a spine. It’s time for them to do what we elected them to do."

Jindal also criticized Obama for not doing enough to confront the Islamic State terrorist group with military force. He said he rejected the State Department's argument that America could not "kill our way to victory," and argued ground troops might be necessary to win the fight.

"How have we ever won any war…if not killing our way to victory?" Jindal asked.

 Jindal came near the end of a long list of potential 2016 hopefuls who addressed conservatives gathered Thursday at National Harbor in Maryland. son of immigrants from India, Jindal spoke at length about the need for new immigrants to adopt American culture and learn to speak English. 

"They must assimilate. They must integrate. We used to be the melting pot. Now, the politically correct crowd says we oughta be a salad bowl. There is nothing wrong with saying. if you want to come to America you should be an American," Jindal said. "I am tired of hyphenated Americans. We’re not Indian-Americans or African-Americans, we’re all Americans."
