Lawsuit over Walker-related probe to be argued

MADISON, Wis. — Prosecutors investigating Gov. Scott Walker's recall campaign and more than two dozen conservative groups hope to convince a federal appeals court to overturn a judge's ruling that temporarily blocked the probe.

The arguments Tuesday before the 7th U.S. Circuit Court of Appeals come exactly two months before Walker faces re-election against Democrat Mary Burke.

The investigation and legal fight has dogged Walker, even though no one has been charged and prosecutors have said Walker is not a target.

Prosecutors want the appeals court to reverse the preliminary injunction and dismiss the federal civil rights lawsuit filed by the Wisconsin Club for Growth and its director, Eric O'Keefe.

The appeals court was also scheduled to hear arguments over a media coalition's request that all records in the case be made public.
