ISIS released a videotaped message today threatening an attack on Washington DC, and warning that all countries involved in the war against the terror group are liable to attack. In the US, heightened airport security is being instituted, and a flight from Washington to Boston was evacuated, with two passengers questioned and then released. Crew members reported that the two passengers had been behaving in a suspicious manner. It has been known among security specialists that groups planning terror attacks will often prepare by testing procedures this way. Passengers throughout the US are being asked to be especially vigilant, and to report anything that seems out of character. In the video, an ISIS member identified as "Al Ghareeb the Algerian" shouts "as we struck France in the center of its abode in Paris, we will strike America in its center in Washington."

On Good Morning America on Friday morning, President Obama downplayed the danger of ISIS in general, saying that the organization is getting weaker. Unfortunately, it doesn’t require much organizational strength to carry out significant terror attacks. After the Paris attacks, he described the situation as "a terrible, sickening setback."
