Did Iran infiltrate its operatives into VOA Persia Service?

Washington Free Beacon:

A group of nearly 100 prominent Iranian dissidents is demanding that Congress launch investigations into clandestine efforts by the Islamic Republic to influence U.S. policy using a network of lobbyists and propaganda pieces placed in Voice of America's Persian service, according to a letter sent to leading lawmakers and obtained by the Washington Free Beacon.

The group of dissidents, composed of prominent Iranian voices that oppose the hardline regime in Tehran, says that Congress is not doing enough to expose the Iranian regime's lobbying efforts in D.C. and propaganda network, which is said to include some at VOA Persia.

Iranian-American groups claiming to represent American interests are said to be carrying water for the Islamic regime inside the White House and on Capitol Hill, according to these dissident voices.

The letter cites VOA's Persian service as a source of pro-Iran corruption. The Free Beacon has reported multiple times on claims that VOA has been infiltrated by Iran regime loyalists who seek to spin coverage in a favorable way for Tehran. In one instance, an Iranian dissident was barred from appearing on VOA Persia for voicing critical opinions about the regime.

The letter comes at a time when the Trump administration is seeking a tougher approach on Iran for its repeated violations of international accords governing the nuclear deal. The dissidents maintain that U.S. officials have been too soft on the regime and ignored its surreptitious efforts to make American diplomacy more generous to Tehran.

What they may be doing is giving the Trump administration a heads up on a problem that could have been created by President Obama and Ben Rhodes to help sell the bad Iranian deal.  They both seemed unusually open to working with the regime of genocidal religious bigots who run Iran.
