#1: Congress passes laws.
From how fast you can drive on highways to whether basset hounds should have a national holiday.
#2: Congress decides how to spend our money.
Should we spend our money to go to outer space or to build more national parks?
#3: Congress shapes foreign policy.
The President may be the "Commander in Chief" of the military, but it's Congress that has the power to declare war.
Congress also deals with things like trade policy and foreign aid.
Congress does a lot…so the next time you go by the US Capitol, you'll know what goes on in there
