Story highlights Brady Campaign to Prevent Gun Violence will endorse Hillary Clinton's presidential bid Tuesday

It's the third prominent endorsement related to gun control in recent days

Clinton is using the issue of gun control to show contrast with her primary opponent Bernie Sanders

Des Moines, Iowa (CNN) The Brady Campaign to Prevent Gun Violence will endorse Hillary Clinton for president Tuesday in Iowa, the former secretary of state's campaign announced.

The endorsement provides Clinton with yet another data point to contrast herself with Vermont Sen. Bernie Sanders on the issue of guns, something Clinton has been doing since the first Democratic debate in October.

"Hillary Clinton has been a national leader on gun violence prevention for decades," Brady Campaign President Dan Gross said in a statement. "More than any candidate on either side of the aisle, she has the experience, record, and demonstrated commitment to help reach the Brady Campaign's goal of cutting gun deaths in half by 2025."

Gross will speak at Clinton's first event of the day in Ames, Iowa, according to Clinton aides.
