A member of the US Congress Saturday accused immigration officials of allowing California attacker Tashfeen Malik into the country despite critical missing information in her request for a fiancee visa, AFP reports.

"After reviewing Tashfeen Malik's immigration file, it is clear that immigration officials did not thoroughly vet her application," House Judiciary Committee chairman Bob Goodlatte said in a statement.

Malik, a 29-year-old Pakistani national, came to the United States last year on a fiancee visa, which Goodlatte said was issued despite a lack of proof that she had ever met her US-born husband, Syed Farook, 28.
