House Judiciary Committee Chairman Chuck Grassley is demanding information about the Obama administration’s oversight of foreign nationals who receive flight training in the United States.

In a letter to the Department of Homeland Security, Grassley, R-Iowa, said an Oct. 11 airplane crash in East Hartford, Conn., has raised his suspicions about flight school training of the pilot, Feras M. Freitekh, a Jordanian national living in the United States.
