What were gingrichs ethics violations?

Newt Gingrich faced ethics violations primarily related to his use of tax-exempt organizations for political purposes and misleading the House Ethics Committee. In 1997, he was reprimanded and fined $300,000 after an investigation found he had provided false information regarding a fundraising project linked to a college course he taught. This incident raised concerns about the improper use of tax-exempt funds for partisan activities and contributed to his eventual resignation from Congress in 1998.
