Some protesters opposed to war with Iraq spent the night in the Wisconsin offices of Senator Herb Kohl.
Five demonstrators camped out overnight in Kohl's Milwaukee office, while four spent the night in a conference room in his Madison office.
Protester Diane Farsetta says they plan on occupying the Madison office until the Senate votes on the measure giving President Bush broad authority to use military force against Iraq -- or until Kohl says he'll vote against it.
Kohl says he hasn't decided whether to support the resolution.
Other demonstrators visited Kohl's offices in Eau Claire, La Crosse and Appleton Tuesday.
