In his plea, defense contractor Mitchell Wade, admitted to paying his employees to make campaign contributions to two Republicans, though he says these two did not know the contributions were illegal. In the 2004 cycle Katherine Harris(R-Fla) received $32,000 from employees of MZM, Inc and Virgil Goode(R-Va) received $23,551. Goode also received $34,625 in the 2006 cycle. The above information is from Open Secrets.
According to Paul Kiel of TPM's Daily Muck:
After Wade made the campaign contributions, Wade asked that one of the Representatives and his staff request appropriations funding for an MZM facility. The Representative's staff later confirmed to Wade that an appropriations bill would include $9 million for the facility.
