Here's The Milwaukee Journal Sentinel's report:
In an interview Wednesday, O'Keefe declined to say why his group has focused on Ellis, saying it has called out politicians from around the country for their hypocrisy....Ellis has been a Wisconsin state senator since 1982, he's up for reelection this November, and there is a challenger from the Democratic Party.
Some conservatives have called for a primary challenge to Ellis, who has been at odds with other Republican leaders on issues such as expanding voucher schools....
The unedited video shows Ellis responding favorably to remarks critical of Republican Gov. Scott Walker. The individual secretly recording the interview for Project Veritas accuses Walker of focusing all of his efforts on a possible presidential bid.
"Amen," Ellis responded, later applauding comments about Walker not caring about Wisconsin. Ellis added, "I think Walker's working for Walker."
UPDATE: One day later, Mike Ellis drops out.
