The 2016 presidential candidates reacted to President Obama’s Oval Office speech on ISIS Sunday night.

“This is not a time for ideological silliness,” Florida Sen. Marco Rubio said in a statement. “This is a time for serious action because the future security of our country is at stake.”

Kentucky Sen. Rand Paul said the speech attempted to switch the focus to gun control.

“The #Obamaspeech was an attempt to turn a necessary discussion on terrorism and national security into a ineffective gun control debate,” Paul wrote on Twitter.

Democratic candidate Bernie Sanders, meanwhile, praised Obama’s decision not to send troops into Syria.

“We must learn the lesson of Iraq,” Sanders said. “American troops should not be engaged in perpetual warfare in the Middle East.”
