Washington, November 26 (RHC)-- Amid threats by Daesh terrorists to launch attacks on the United States soil, the country is stepping up security measures. Homeland Security Secretary Jeh Johnson said Wednesday that the security forces would be "working overtime" over the Thanksgiving holiday.

Johnson echoed earlier remarks by U.S. President Barack Obama that there was "no specific and credible intelligence indicating a plot on the homeland." Before boarding a train to his home outside Newark, New Jersey, Johnson said at a short press conference at Washington's Union Station that he knew "of no specific credible threat of a plot on the U.S. homeland by a terrorist organization."

"However, those of us in law enforcement, homeland security and the intelligence community continue vigilance. We work overtime." According to The Hill, nearly 47 million people travel in the days surrounding Thanksgiving, which raises concerns particularly about attacks on airplanes, train stations, and other modes of transportation.

"We also want to encourage the public this holiday season: Be vigilant yourself and aware," Johnson said. "'If you see something, say something' has to be more than a slogan."
