MADISON, Wis. (AP) -- Wisconsin elections officials have unveiled the previously secret location where workers are checking an estimated 1.9 million signatures on petitions seeking the recalls of Gov. Scott Walker and five others.

The work is being done on the east side of Madison about two miles from the Capitol. The 100-year-old brick building, tucked into a neighborhood right behind a popular bar, is also home to the state's printing facility and motor pool.

There is a high level of security at the building, which is behind a closed gate topped with barbed wire. Capitol police are stationed at the entrance.

Inside, about 50 temporary workers have completed the task of scanning all the petitions. They are now in the process of checking signatures and flagging any that may be disqualified.
