Rep. Chaka Fattah resigned from Congress Thursday, effective immediately.

The Pennsylvania Democrat, who has represented West Philadelphia since 1995, was found guilty Tuesday of all the federal corruption charges he faced. Fattah lost his seat in the April primary to state Rep. Dwight Evans.

Fattah is out on bail ahead of his October sentencing. The charges he was found guilty of included bribery, racketeering, conspiracy, money laundering and bank fraud — all stemming from efforts to repay an illegal $1 million campaign loan.

He had previously tendered a resignation that would have become effective Oct. 3, despite calls from House Speaker Paul Ryan to resign immediately.

In a letter sent to Ryan late Wednesday, Fattah, 59, said he was "working to clear" his name and planned to appeal the guilty charges.
