In February 2013 Karabulut stated she would refuse to pledge loyalty to the soon-to-be-King, Dutch Crown Prince Willem Alexander, during his inauguration ceremony. She cited that the procedure was overly ceremonial as she had already pledged allegiance when she was admitted to the House of Representatives. She was also a convinced republican.
Karabulut temporarily resigned from the House of Representatives for a maternity leave, she was replaced on 3 September 2013 by Tjitske Siderius. Karabulut returned from leave on 26 November 2013.
