(Radio Iowa) – For nearly two-and-a-half centuries, it’s been tradition to wear professional, business attire on the floor of the U-S Senate, and Iowa Senator Chuck Grassley says he’s in “shock” the Senate Majority Leader would drop the dress code. Grassley, a Republican, says Democrat Chuck Schumer of New York should not have abandoned the long-standing policy of respecting the institution by wearing the proper attire.

Even with the relaxed rules, Grassley wouldn’t consider wearing one of his John Deere hats into the chamber.

Grassley turned 90 on Sunday and says it’s important to carry on traditions as they’ve stood the test of time for a reason.

Reports say the updated rule only applies to senators, as staffers have to continue to follow the dress code.
