Aides for then-Secretary of State Hillary Clinton allegedly threatened the Bangladeshi prime minister's son in 2012 with an IRS audit in an attempt to stop the country's financial mismanagement probe into Grameen Bank, The Daily Caller reported Wednesday.

At the time, Clinton Foundation donor Muhammad Yunus was serving as managing director of the bank.

The accusations were made by Sajeeb Wazed Joy, son of Bangladesh Prime Minister Sheikh Hasina, who said it was "astounding and mind boggling" that senior State Department officials repeatedly pressured him to influence his mother to halt the investigation.

Joy, a permanent American resident, said he had been in the U.S. for 17 years at the time without ever having a problem, but that they would stress that he might get audited and "They would say over and over again, 'Yunus has powerful friends' and we all knew they were talking of Secretary Clinton."

Hasina said her son was pressured several times over the issue and that American officials also threatened to cut off funding for an important bridge project if Yunus was removed from his position at the bank, according to the Dhaka Tribune.

Yunus was one of the people cited in an AP report in August during the presidential campaign that said more than half the people outside the government who met with Clinton while she was secretary of state gave money to the Clinton Foundation.

At the time the Clinton campaign criticized the report as misleading and unfair, emphasizing that for many of the people on the list their importance was the reason for the meetings and not their contribution to the Clinton Foundation.

Democratic strategist James Carville specifically used the example of Yunus at the time to illustrate the point, telling "Fox and Friends" that he "is the person who started microlending, which probably helped more people in poverty than anyone, and he won a Nobel Peace Prize in 2008 . . . If the State Department can't help a Nobel Prize-winning economist who is being subject to oppression by the host government who can they help?"
