The last time there was a fight in the Senate, they changed the rules to ban calling each other corrupt

• A fistfight nearly broke out in the US Senate on Tuesday but was stopped by Sen. Bernie Sanders.
• The last time there was actually a fight in the Senate, two Democrats brawled, hitting bystanders. 
• The 1902 incident led the Senate to adopt a rule banning members from insulting each other.

A fistfight nearly broke out between a Republican senator and a Teamsters leader during a hearing in the US Senate on Tuesday, until 82-year-old Senator Bernie Sanders broke it up by yelling "You're a United States Senator!"

But real fisticuffs have actually gone down on the Senate floor before.
