A Republican member of Congress on Thursday night claimed the Islamic State terror group was behind the Las Vegas massacre of 58 people in October. “I smell a rat, like a lot of Americans. Nothing’s adding up,” Rep. Scott Perry (R-PA) told Fox News’ Tucker Carlson. Claiming to have what he “believes” is “credible evidence,” Perry cast doubt on investigators’ assertions that Stephen Paddock was the lone gunman in the attack and suggested a “terrorist nexus” was involved. He claimed to personally have information about “terrorist infiltration through the southern border.” “Let’s face it, ISIS, twice before the attack, warned the U.S. they would attack Las Vegas… and then after the attack claimed responsibility four times. Meanwhile, the local law-enforcement investigative services are telling us there is no terrorist connection.” When pressed to provide more details on what “evidence” he has to support this theory, Perry said he was “not able” to reveal anything.
