Jill Duggar and her husband have left the U.S. for a long-term mission trip in the wake of sex abuse revelations against her brother.

The 24-year-old Jill and her husband, Derick Dillard, will leave for an undisclosed country for a lengthy stay with their infant son, who was born April 6.

Jill Duggar Dillard and her sister, Jessa Seewald, admitted to Fox News that they were among their brother’s molestation victims more than a decade ago at their family’s home.

According to police reports released in May, the 27-year-old Duggar molested four of his sisters and a babysitter as they slept.

Duggar admitted to sexually abusing the girls but was never prosecuted because police did not learn about the claims until the statute of limitations had run out.

A report published last week by InTouch showed that a non-relative victim intended to sue Josh Duggar in civil court.

Jill Duggar would almost certainly be called to testify in that case, but she and her husband insist their mission work had been planned for a long time.

“God has put a desire in our hearts to serve Him internationally for longer than the typical short-term mission trip,” Derick Dillard said on the family’s website. “We were prepared for the possibility of it being years before our family would be able to make a move of that magnitude."

TLC has suspended the family’s “19 Kids and Counting” reality show in the wake of the revelations, and Jill and Jessa had been rumored as possible stars of a spinoff program.
