D.C. businessman Jeffrey Thompson is said to have reimbursed employees and associates for straw donations to local and federal candidates.
Another associate of D.C. businessman Jeffrey Thompson is expected in court later today to plead guilty to making "straw" donations to candidates running for office.
Stanley Straughter is the second Thompson-associate in recent days to be charged with making illegal campaign contributions to congressional candidates in 2010.
Straughter is a Philadelphia-based contractor who worked with Thompson's former accounting firm.
Thompson—a major city contractor and fundraiser—is at the center of a federal investigation into D.C. government corruption.
Last week, an employee at Thompson's former accounting firm pleaded guilty to making $160,000 contributions in straw donations that were later reimbursed by Thompson.
In a statement after the plea, U.S. Attorney Ron Machen said the accounting firm had been converted into "an assembly line for illegal campaign contributions."
Thompson hasn't been charged by prosecutors and sold his ownership stake in the accounting firm.
Straughter was charged in a criminal information—a document that typically means a defendant intends to plead guilty. The hearing is set to begin at 2 p.m.
