(CNN) - Rep. Paul Ryan doubts President Barack Obama will be able to maintain his promise that there will be no American boots on the ground in the fight against ISIS.
"I'm supportive of what the President has done going into Syria and Iraq, but you have to see this thing through," the Wisconsin Republican said Tuesday on CNN's "Erin Burnett OutFront."
Obama suggested in an interview with CBS' "60 Minutes" that his policy of sending no U.S. combat troops will stay in place. The situation in the region is more a political problem than a military one, he said.
According to a CNN/ORC International poll, the overwhelming majority of Americans (73%) support the current airstrike campaign but less than four in 10 favor sending combat troops into Iraq and Syria.
If Obama's administration ultimately comes to Congress with a plan to send combat troops to Iraq and Syria, Ryan said he would support it.
"I think the President should come to Congress with an authorization of force resolution and I would support it," he said. "And I would help the President pass that because I think it's necessary to see this threat through."
"We need to destroy ISIS, and we need to do what it takes to destroy ISIS," he continued.
Tens of thousands of protesters bracing for more violent clashes with police in Hong Kong. In defiance of the Chinese government, the demonstrators are blocking Hong Kong's major highways in historic political protests.
Police have fired tear gas and pepper spray in a crackdown, but demonstrators are not backing down. The pro-democracy protesters say Hong Kong should be allowed to elect its own leader.

On the night of September 11, 2012 Ambassador Chris Stevens, former Navy Seals Glen Doherty and Tyrone Woods and Information Officer Sean Smith were murdered in Benghazi, Libya. What happened that night? Could it have been prevented? And who was to blame? Erin Burnett hosts CNN’s exclusive documentary, “The Truth About Benghazi”.
The U.S. has conducted 200 airstrikes in Iraq and 43 in Syria since the war against ISIS began. The strikes have hit the enemies of Bashir al Asaad. Earlier Friday, Secretary of Defense Chuck Hagel said the U.S. still wants Assad gone.
There has been no coordination, "nor will there be," between Washington and al-Assad's government regarding U.S. airstrikes in Syria, U.S. Secretary of Defense Chuck Hagel said Friday. The United States hasn't shifted its approach to al-Assad, who has "lost all legitimacy to govern," according to Hagel.
But will airstrikes ultimately end up helping the Assad regime?
CNN's Tom Foreman has the report OutFront.
FBI director James Comey says he is "not confident at all" that airstrikes in Syria disrupted an imminent plot to attack America. The administration said stopping that plot was the reason for its first major strikes on Syria.
Comey went on to say an attack in the U.S. could happen at any time, as soon as "tomorrow."
