"Hours later, the Department of Homeland Security confirmed to Fox News that Ullah was admitted to the U.S. after presenting a passport displaying an F43 family immigrant visa in 2011.

That prompted White House Press Secretary Sarah Sanders to note that President Trump has railed against so-called “chain migration,” through which dozens of an immigrant’s relatives can enter the U.S. simply because their family member made it.

“The President’s policy has called for an end to chain migration,” Sanders said. “If that had been in place, that would have prevented this individual from coming to the United States.”"

He did come in through chain-migration according to the DHS, and Trump has been saying his opposition to chain migration would've stopped the terrorist, not his travel ban. You're wrong on everything, apparently.
