Many questioning why attacker Tashfeen Malik's social media was not checked before she was allowed into the U.S.

The FBI’s director said communication between Malik and Syed Farook was done through private messages.

Despite that revelation, leaders are still standing by calls to make social media checks part of the visa screening process.

Many are saying future employers check social media, questioning why the government doesn’t.

Senator Chris Murphy and Senator Richard Blumenthal joined several other lawmakers in signing a letter, urging the Department of Homeland Security immediately require a review of visa applicants' social media before they are allowed into the country.

"These extremist groups are sometimes pretty sloppy in terms of the trail they leave online whether it be Twitter, Facebook, or other messaging boards,” said Murphy. “If a visa applicant has an easily discoverable online public history of talking to extremist groups then they shouldn't be let into the United States."
