WASHINGTON, DC (CBS) — A government watchdog agency is questioning whether Bucks County congressman Michael Fitzpatrick broke House ethics laws by soliciting money in his invitation to his swearing-in reception.

Fitzpatrick was the focus of attention on the House floor on Friday when House Republicans had to correct his first-day-on-the-job gaffe by nullifying votes that were cast before he was officially sworn in.

Fitzpatrick (right) and Texas congressman Pete Sessions (left) were greeting Fitzpatrick supporters on Wednesday afternoon while their colleagues were officially being sworn in on the House floor.

Retracting their votes did not affect any outcomes.

Meanwhile, the Sunlight Foundation is questioning whether ethics laws were broken.

A Fitzpatrick spokesman says the event inside the Capitol was free and not a fundraiser and the money was for campaign-provided buses to DC.
