U.S. Rep. Mark Sanford lashed out Wednesday at his ex-wife, saying her demands that he have a psychiatric evaluation and for modified custody arrangements are “crazy.”

“Since the time of the divorce I have tried to do everything in my power to be both a good dad and a former husband,” Sanford, 54, said in a statement. “It seems that nothing I can do at this point is enough, appropriate or adequate. The different accusations and requests made are, by their very nature preposterous, crazy, and wrong.”

Calls to Jenny Sanford were not answered.

The latest complaint, filed Aug. 28, demands the former S.C. governor undergo a mental evaluation and anger-management classes.

Filed as an effort to modify the couple’s child-custody arrangement, Jenny Sanford’s petition in family court also seeks to change the terms under which Rep. Sanford can see his youngest son.

The new filing states the 16 year old should not be subjected “overnight to a member of the opposite sex not related to the Plaintiff or Defendant through blood or marriage who could reasonably be construed as a paramour,” according to reports from a local CBS affiliate.

The language appears to be a jab at Sanford’s Argentinian mistress-turned-fiancee, Maria Belen Chapur.

The filing also seeks a court order barring the use of “illegal or unprescribed prescription drugs” or excessive alcohol consumption while the son is visiting either parent.

While he was S.C. governor, Sanford vanished for six days in 2009. His spokesman told the press that Sanford was “hiking the Appalachian trail.” Instead, Sanford, at the time married, was with Chapur in Buenos Aires. After his return to South Carolina, Sanford admitted to the affair, separated from his wife and, in 2010, the couple divorced.

Sanford disappeared from public view after finishing out his term as governor in 2011. However, the Charleston Republican was resurrected from the political dead in 2013, when he won a special election for a U.S. House seat that he held before being elected governor.

But echoes of the scandal have plagued Sanford. Last year, he was accused of violating the terms of his divorce when he entered his former wife’s home. Sanford later said he had done so to watch the Super Bowl with his then 14-year-old son.

In his statement Wednesday, Sanford did little to hide his anger at his ex-wife’s most recent legal filing.

“I have avoided responding in these sorts of things as best I could over the past five years and I want to continue to do so,” Sanford’s statement continued. “But when accusations are made that would suggest inadequacy in my role as a father or inadequacy in my professional role as a congressman, they have to be addressed. I think anybody who knows me in the Lowcountry knows that these accusations are false.”

A hearing on the matter is set for Sept. 15.
