San Bernardino shooter Tashfeen Malik denied having any militant sympathies or intentions when she was asked in an application form for a U.S. visa two years ago, documents described to Reuters on Tuesday showed.

Information in the documents could bolster complaints of critics in Congress who said flaws in the immigration system meant Malik was not thoroughly investigated. The papers also showed that statements by Malik and her husband and fellow shooter, Syed Farook did not raise any alarms among authorities that they were potential Islamic State militants.

U.S.-born Farook said they first met in person and became engaged during the October 2013 Haj pilgrimage to Mecca with their respective families, according to other documents released by a congressman on Tuesday.
