The Girl Scouts of the USA said they're open to questioning from the U.S. Conference of Catholic Bishops about their alleged ties to abortion and gay rights groups.

U.S. Catholic Bishops is investigating whether the Girl Scouts have connections with the abortion provider Planned Parenthood. They will also look into the Scouts' "problematic program materials."

The Girl Scouts have denied any relationship with Planned Parenthood and insist their sole focus is the betterment of young women.

"We do not take positions on some of these issues that we're being alleged to take positions on," Anna Maria Chávez, CEO of Girl Scouts of the USA, said at a National Press Club luncheon Wednesday.

"We've found that if you compare Girl Scout alumni to non-alumni, they outperformed in nearly every single measurement," Chávez added.

"They were making more money...they had a higher educational attainment than non-alums, they were happier, and they were contributing to their community," she said.
