A spokesman for Hillary Clinton's campaign pushed back Tuesday on criticisms of the Clinton Foundation, arguing the controversial charity will not "completely close up shop" should Clinton win the election in November.

Brian Fallon, a spokesman for the Clinton campaign, said the pledge to curb foreign and corporate donations to the foundation will provide adequate cover for Clinton in the event she becomes president.

"It is no small feat to even entertain these kinds of changes," Fallon said during an appearance on MSNBC. "It is not something they want to completely close up shop."

Critics pointed to a new batch of emails made public Monday that revealed the close contact Clinton Foundation employees kept with State Department staff under Clinton. Donors were afforded access and favors from Clinton's closest aides.

For example, the prince of Bahrain sought an audience with Clinton through the foundation after he failed to secure a meeting through "normal channels" at the State Department. Another wealthy donor pushed for help obtaining a visa for one of his clients after the U.S. embassy in London flagged the client's criminal background.

But Fallon argued Tuesday that the latest round of revelations was an "act of desperation" from the campaign of Donald Trump.

Trump has begun to hammer the Clintons for the wealth they amassed in the years since establishing the foundation, calling Monday on the Justice Department to appoint a special prosecutor for a probe of the charity.
