COLUMNIST: I've Been Added To The US 'Terrorist Watch List'
"Just informed I'm on the @DHSgov terrorist watch list. Explains why I have been subject to extra screening each of my recent trips," Hayes wrote on Twitter.
Hayes, who is also a Fox News contributor, speculated on the matter in subsequent tweets. He suggested his recent one-way trip to Turkey could have triggered extra attention. He also said he attempted to fix the issue on the DHS website but hit a technical glitch.
DHS did not immediately respond to a request for comment from Business Insider.
The US has often been accused of being overly loose in how it assigns individuals to the list, designed to boost the "ability of front line screening agencies to positively identify known or suspected terrorists trying to obtain visas, enter the country, board aircraft, or engage in other activity," according to the federal government.
