Democratic presidential front-runner Hillary Clinton says she expects President Barack Obama to announce "an intensification" of the U.S. strategy against Islamic State militants following last week's attack in California.

Clinton tells ABC's "This Week:" ''We have to have a much more robust air campaign against ISIS targets, against oil infrastructure, against leadership. And I think that's what you'll hear from the president.

The former secretary of state says she also would require the online community to keep militants from communicating on social network sites. She says sites like Facebook, Twitter and YouTube "cannot permit the recruitment and the actual direction of attacks or the celebration of violence" by Islamic militants. Authorities say a married couple were responsible for the attack in California, and the woman had pledged allegiance to the Islamic State group on Facebook as they went on their rampage

The White House says Obama will provide an update on Wednesday's shootings in San Bernardino and discuss the broader threat of terrorism, including how it has evolved and how he plans to defeat it.

Republican presidential front-runner Donald Trump says he'd be open to racial profiling and investigating the families of people who carry out jihadi attacks.

The former reality star tells CBS' "Face the Nation" that he'd be, "very tough on families" of attackers, adding he'd "go after the wives" of attackers.

He also said people near the attackers sometimes know there's something wrong but refuse to report them for fear of "racial profiling." Trump says he' thinks that's "pretty bad," and that people have died as a result.

Trump says he's not playing on people's fears, "I'm playing on common sense." He tells CBS that he has Muslim friends who "are great people" and are concerned about extremism, too.
