FEC data guru joins watchdog group

Long-time Federal Election Commission (FEC) aide Bob Biersack has joined the Center for Responsive Politics, a campaign finance watchdog group.

Biersack, the agency's data guru and a favorite among reporters, will serve as a senior fellow with the group to help expand its research and offer his expertise on campaign finance data and rules.

"Bob has seemingly endless knowledge of the intricacies of campaign finance rules and data and is greatly respected in this field," said Sheila Krumholz, the group's executive director, in a statement.

"Over my career at the Federal Election Commission, I have come to know and value the work of Center for Responsive Politics," Biersack said. "I look forward to joining forces with the staff of the Center on the front lines of tracking money in federal politics."

Biersack, who was special assistant to the FEC's staff director, worked at the agency for more than 30 years. He spent nearly 20 years as the agency's chief statistician and another five as the head of the FEC's press office.
