They don't do that very often. In fact, last year was the first time since at least 1997 that they turned down the extra money.
Meanwhile, Congress hasn't raised the minimum wage since 1996. It's been stuck at $5.15 an hour ever since.
So Sen Hillary Clinton (D-NY) introduced a bill -- S. 2727 -- that would tie minimum wage increases to Congressional pay.
"To amend the Fair Labor Standards Act of 1938 to provide for an increase in the Federal minimum wage and to ensure that increases in the Federal minimum wage keep pace with any pay adjustments for Members of Congress. " -- S. 2725
In other words, every time Congress gets a raise -- the lowest paid working Americans get one, too.
Congress members don't want to raise the minimum wage -- no problem. Members just have to pass on their own pay raises. (DailyKos)
