MADISON, WI (WTAQ) - Though no charges have been filed, newly-released e-mails and other documents show Wisconsin Governor Scott Walker and his family were the targets of numerous death threats during his first two years in office.

Most of the threats came right after he took office in 2011 and were related to his proposal which weakened public employee union collective bargaining. That change sparked huge protests at the Capitol which lasted several weeks.

A Wisconsin Department of Justice spokesperson says there are no open investigations into threats against Walker now.
