A Georgia Democratic congressman who said this week that wage disparities between men and women “belong in a ‘Mad Men’ episode” paid his female aides on average $8,221 less than men last year, according to a Tipsheet review of congressional salaries for the previous year.

Rep. Hank Johnson, who faces first serious primary challenge this year since he was first elected in 2006, launched a full-court press this week in support of the Paycheck Fairness Act, a Democratic proposal aimed at narrowing the pay gap between men and women.

“According to a report from the American Association of University Women, the women in the Fourth Congressional District still earn only 88 cents for every dollar earned by men,” Johnson said in a statement Tuesday. “Today, women make up about half the workforce and it’s wrong that on average they are still being paid less than men.

“A woman deserves equal pay for equal work. As President Obama has stated, ‘It’s time to do away with workplace policies that belong in a ‘Mad Men’ episode.'”

But women working in Johnson’s district actually fared better than those working in his congressional office, where female staff made 87 cents on a man’s dollar last year.

Johnson’s female aides earned on average $53,493.98 last year while men on average took home $61,715.87 annually, according to an analysis of congressional wages that excluded part-time employees, shared employees whose salaries were paid by multiple members and committees, and those who held their Capitol Hill posting for less than a full calendar year.

As a Tipsheet feature will demonstrate over the following days, Johnson’s Mad Men watch party wasn’t a lonely affair: he shared the couch with Georgians of both parties.
