LINCOLN, Neb. (AP) — A spokeswoman for U.S. Rep. Jeff Fortenberry says it appears the congressman’s opposition to abortion motivated someone to send a so-called glitter bomb to his Lincoln office.

She says no one was hurt in the Wednesday prank, except some staffers now have sparkles on their clothes. The glitter-filled envelope was reported to Lincoln police, the U.S. postal inspector and the FBI.

A note was included in the envelope that read: “Congrats, you’ve earned this for trying to deny women their right to choice. Mind your own uterus.”

Lincoln police say the letter doesn’t appear threatening, but investigators will analyze it for fingerprints.

Fortenberry recently supported a House of Representatives effort to prohibit federal funding for abortions. He said people are free to disagree with him.
