President Barack Obama spoke on Wednesday from the White House about U.S. homeland security heading into the holiday season and urged vigilance. "Right now, we know of no specific and credible intelligence indicating a plot on the homeland,” the president said Wednesday afternoon, saying U.S. intelligence officials "are constantly working to protect all of us," "working overtime."
"But for many of us," Obama said, "the events in Paris have touched a deep chord."
“We continue to do everything possible to prevent attacks at home and abroad and to prevent foreign terrorist fighters from entering the United States or other nations."
"In the event of a specific credible threat, the public will be informed. If you see something, say something," Obama said. "That's always helpful."
Obama’s announcement comes two days after the State Department issued a worldwide travel alert, warning travelers of the potential risks of terrorism posed by Islamic State, Al-Qaeda, Boko Haram.
