Washington (CNN) Bernie Sanders will co-sponsor a bill to repeal legal protections for the firearm industry that he'd supported a decade ago, taking another step to undo the political damage of that vote and smooth over his relationship with gun control advocates.

Tad Devine, Sanders' top strategist, confirms that Sanders has agreed to be a co-sponsor of the repeal bill.

According to a release from the Brady Campaign, Sanders will co-sponsor the repeal of the Protection of Lawful Commerce in Arms Act, which protects gun manufacturers in lawsuits involving shootings. Sanders had voted in favor of the protections while in the Senate and has up to this point resisted reversing course on the issue.

The Brady Campaign says that Sanders decided to support the legislation "hours after meeting with Brady activists," and that his staff also met with victims of gun violence.

For Sanders, it's all an effort to undo the damage of a 2005 vote for a bill that protected gun manufacturers from lawsuits when their firearms are used in crimes. Then-New York Sen. Hillary Clinton opposed that bill, and has repeatedly pointed to Sanders' vote as evidence he was aligned with the National Rifle Association.
