MIAMI — The chairman of the Republican Party of Florida on Monday called for U.S. Rep. Trey Radel to step down following his recent cocaine conviction.

Chairman Lenny Curry joined a growing number of Republican leaders from Radel’s district demanding his resignation.

“The people of Florida’s 19th Congressional District need a Congressman who is 100 percent focused on the needs of Southwest Florida,” Curry said in a news release. “Therefore, Congressman Radel should step down and focus his attention on rehabilitation and his family.”

Radel pleaded guilty to cocaine possession last week, acknowledging that he purchased 3.5 grams of cocaine last month from an undercover police officer. He has since taken a leave of absence.

As part of a plea agreement, Radel admitted he agreed to buy the cocaine for $250 in a Washington neighborhood on Oct. 29. After the undercover officer gave Radel the drugs, federal agents confronted him, court documents show.
