"It comes seven years after the fact. But the Federal Election Commission this evening ordered the 2004 presidential campaign of Rep. Dennis Kucinich (D-Ohio) to pay up for what it says was Kucinich's improper use of public matching funds.
Kucinich must repay $52,443 to the U.S. Treasury within 30 days, the FEC ruled. The FEC wrote that Kucinich's campaign used public matching funds after March 4, 2004, when he was no longer eligible to use them thanks to his poor showing -- less than 10 percent of the vote in two consecutive primaries -- in the race."
