CNN — U.S. Rep. Trey Radel, who pleaded guilty to cocaine possession, left a rehab facility in Florida on Thursday.
Radel's spokesman, Greg Dolan, confirmed the Congressman completed his in-patient treatment in Naples.
A Republican tea party favorite, the freshman lawmaker announced he would take a leave of absence after admitting to buying cocaine from an undercover agent last month in Washington.
He was placed on probation.
The House Ethics Committee plans a formal investigation.
The chairman of the Republican Party of Florida has called on Radel to step down.
He is up for reelection next November.
