It appears Hillary Clinton might not be out of the woods just yet.

According to The Daily Caller, the Senate Judiciary Committee Chairman Chuck Grassley (R-IA) has launched a new investigation into possible corruption during Clinton’s tenure as Secretary of State.

Last month, The Daily Caller broke the story that alleges that back in 2012, Clinton’s top aides at the State Department were sent to “threaten” Bangladesh Prime Minister Sheikh Hasina with an IRS audit of her son Sajeeb Wazed, who is a permanent US resident, if a Bangladesh government commission didn’t end its investigation into Grameen Bank and its director Muhammad Yunus, who is a major donor to the Clinton Foundation.

Wazed, who has been living in the United States for 17 years, told The Daily Caller that it was “astounding and mind boggling” that senior State Department officials repeatedly attempted to pressure him to influence his mother to end the investigation. He alleged that he was personally threatened with the “possibility” of an audit from the Internal Revenue Service.”

“I have been here legally for 17 years and never had a problem. But they said, ‘well, you know, you might get audited,'” he adds. “They would say over and over again, ‘Yunus has powerful friends’ and we all knew they were talking of Secretary Clinton.”

Senator Grassley sent a letter on June 1 to Secretary of State Rex Tillerson in response to The Daily Caller‘s recent report.

In the letter, he writes:

“If the Secretary of State used her position to intervene in an independent investigation by a sovereign government simply because of a personal and financial relationship stemming from the Clinton Foundation rather than the legitimate foreign policy interests of the United States, then that would be unacceptable.”
