"I've hit a bottom where I realize I need help," Radel told a judge in acknowledging that he purchased 3.5 grams of cocaine from an undercover police officer.
As part of a plea agreement Radel acknowledged he agreed to buy the cocaine for $250 in a Washington, D.C., neighborhood on Oct. 29. After the undercover officer gave Radel the drugs federal agents confronted him, court documents show. Radel agreed to talk with the agents and invited them to his apartment, where he also retrieved a vial of cocaine he had in the home, the documents said.
The charges against Radel were made public Tuesday, and Radel said in a statement then that he struggles with alcoholism and will seek treatment and counseling. Radel made no mention of his political future and did not answer reporters' questions outside of court about whether he would stay in office.
"I want to come out of this stronger," Radel said in court, later adding that he wants to "continue serving this country."
A DEA official who spoke on the condition of anonymity because he was not authorized to release details of the case in his own name said Radel was identified to authorities as a cocaine buyer by his suspected dealer. The dealer had been arrested previously as part of a separate drug investigation led by a federal task force.
Court documents show that when Radel bought the cocaine on Oct. 29 he met with the undercover officer and an acquaintance with whom he had previously used cocaine. The documents said that Radel purchased cocaine on several previous occasions.
Radel's lawyer, David Schertler, said in court that his client had already entered outpatient treatment in Washington and would also seek treatment in Florida. He said his client sees the charge as an opportunity to seek help for a problem.
If Radel successfully completes his year of probation the charge against him will be dismissed and he can apply to have his record expunged.
"I know I have a problem and will do whatever is necessary to overcome it, hopefully setting an example for others struggling with this disease," Radel said in his statement Tuesday.
Radel appears to be the first sitting member of Congress charged with a drug offense since former Rep. Frederick Richmond, D-N.Y., was convicted in 1982 on charges of tax evasion and drug possession.
A spokesman for House Speaker John Boehner, R-Ohio, said the allegations are a matter for the courts.
"Beyond that, this is between Rep. Radel, his family and his constituents," Boehner spokesman Michael Steel said.
The Florida Democratic Party released a statement Wednesday calling Radel's conduct "an embarrassment to his district and to the state of Florida" and saying he "should resign immediately."
Radel was elected in 2012 to represent Florida's 19th Congressional District, which includes the Gulf Coast communities of Fort Myers and Naples. He was a radio host before becoming a congressman. He identifies himself on his Twitter profile as a "Hip Hop conservative" and "lover of #liberty," and his Twitter account has remained active in the past few weeks, including on the day of the bust.
Among the bills he co-sponsored during his freshman term is legislation that would allow a judge to impose a sentence below a mandatory minimum, including for drug offenses.
If Radel had been arrested in Florida with the same amount of cocaine it would be a third-degree felony punishable by five years in prison under state law.
