As of last night, the resolution had not yet been introduced, so it wasn't clear what exactly the House would be voting on today.
It's certainly within the rights of the House as a body to punish members.
"Each House may determine the rules of its proceedings; punish its members for disorderly behaviour," it says in the U.S. Constitution.
Last week, Speaker Nancy Pelosi publicly said that she considered the issue over, and wanted to move on to talk about health care.
But in the interim, House Democratic Whip Jim Clyburn - also from Wilson's home state of South Carolina - has led the charge to go after Wilson, and at this point, he seems to have won the argument.
As for why Democrats are going after him like this? Come on! It's a lot easier to do this than to come up with a deal on health reform.
