Iowa Republican Senator Chuck Grassley may have just uncovered some dirt on House Democrats.

Grassley is the chairman of the Senate Judiciary Committee and is not only requesting former DNC chair Debbie Wasserman Schultz’s IT adviser Imran Awan’ immigration files. But Grassley is also requesting immigration files from his wife, two brothers and two close friends.

“In light of the alleged illegal activity, the committee seeks to better understand Awan and his associates’ immigration histories,” Grassley said in an Aug. 4 letter to Elaine Duke, acting secretary of the Department of Homeland Security. The letter was made public by the committee Monday.

“Therefore, please provide the Alien File for the individuals listed below,” he continued. “Please also include any temporary files, working files, and all documents and items contained in them that were generated by DHS or in its possession.”

Awan’s wife, 2 brothers and 2 friends are all suspects in Awan’s stolen Congressional equipment investigation.

“Awan began working as an IT aide in 2004,” Grassley said in the letter. “Later, his wife, two brothers, and two friends began working as IT aides for nearly 30 congressmen. Over the span of 13 years, they collected more than $4 million—a sum that is reported to be three times higher than the norm for a government contractor.”

Awan and his crew had access to thousands of emails and files between top democrats on the intelligence, foreign affairs, and homeland security committees.

Senator Grassley had an inkling that there was more information to be had, and thanks to him, this is finally being investigated. It’s also important to note that just hours after his arrest, Awan lawyered-up with Chris Gowan who is longtime friends with the Clinton family.
