His Facebook posting comes after attorneys for Jenny Sanford last week asked a family court judge to limit the lawmaker's visitation with his youngest child. They also want Mark Sanford to undergo psychological tests and take anger management and parenting courses.
In his post, Sanford also wrote about Jenny Sanford that "I will never attempt to detract from her or all the positive things she has done in her life, but having to go frequently to ask a former spouse when you can have time with a son is a recipe for conflict."
Marie-Louise Ramsdale, Jenny Sanford's attorney, said in an email to The Associated Press on Friday that her client has always put her sons first "and will always stand up for the boys' best interests and safety."
