Quite a few things happened yesterday in addition to what Aqizzar posted.
-The 19 Senators present voted to hold the missing 14 Senators in contempt of the Senate, and issues orders for apprehension. This has sparked a legal debate, as the Wisconsin constitution dictates that legislators may not be arrested unless they have committed a crime. This is part of the protections that the State has in place to prevent political strong arming.
-A judge issued a compromise order, where public is no longer allowed to stay in the Capitol past business hours of 8am - 6pm, but during those hours free access can not be denied.
-At 6:00pm when the building was to be cleared of the public, protesters gained control of an entrance, and one of the Capitol's 4 wings was flooded with protesters. Our staff locked down the Senate chambers to prevent the chambers from being taken, but the protesters were contained by police before they got out of the wing. Police, and an assemblyman spoke to the crowd, laid out the particulars of the judge's orders, and most protesters in that wing left willingly at this point. The police continued talking to the protesters who had been spending the night in the rotunda for a few hours until a consensus was reached and all the protesters walked willingly out of the Capitol with the police.
On Wednesday the Senate changed its rules to allow the staff of the missing Senators to be assigned to members who have been present, as well as revoking additional privileges of staff in said offices, such as their parking spaces, among other things.
Today the atmosphere was much better, the Senate canceled the session that was scheduled, and the open access was restored, with all wings open, and police wanding people indoors before they were set free into the Capitol. I am very glad that they are not restricting people any more, as it made things much more messy.
It's going to be in the low 30's tomorrow, which is a nice spring day for us, so I'm expecting that tomorrow is going to be very very big. Last weekend it was a snowstorm, and ~100,000 people attended the rally. There have been many things that have happened this week that have escalated interest in what is going on as well.
