A Bill is an idea drafted by a senator or a representative and introduced to The House of Representatives and The Senators.
The Bill is then then debated and revised in a subcommittee then moved onto a committee where the same process happens.
I like it!
I don't like it!
The Bill is then debate again and either moves onto the full house and full senate or the bill dies. There are also rules in place from the rules committee on how the debate will go; for example, if people can filibuster or not.
Pass it or Kill it?
The Full House and The Full Senate then Vote on the Bill and if it passes then it goes to The President who will sign the bill into law. If the bill goes back and forth, without being passed, from the senate and the house a conference committee drops in and decides the outcome of the bill.
The President then can sign the bill to make it officially a law, veto it, or pocket veto meaning he doesn't say no or yes and stuffs it in his drawer.
I say no to this bill.
If the President vetos it, it can go back to The Senate and can be override by a 2/3 vote
