Senate Republicans stepped up their efforts Wednesday to compel the 14 Senate Democrats who fled Wisconsin two weeks ago to come home.

The Senate voted to impose a $100 per day fee for any senator who is absent without leave for two or more session days. Republicans remaining in the Senate approved the daily fine resolution with none of the Democrats present.

"They're doing this petty stuff," said state Sen. Chris Larson, D-Milwaukee, one of the senators who left to avoid voting on Gov. Scott Walker's controversial budget repair bill.

The new resolution also requires the absent Democrats to reimburse the Senate for any costs incurred in attempts to force them to return, and their travel expenses and per diem payments can be withheld until they pay back the penalties and costs. Salaries would not be affected.

The resolution, drafted by Senate Majority Leader Scott Fitzgerald, R-Juneau, allows any law enforcement officer in the state to find and return any of the missing senators.

Republicans have already withheld the checks of missing Democrats from direct deposit and denied access to copying machines for their staff.
