The mother of Trayvon Martin, the teen shot to death by George Zimmerman in 2012, endorsed Hillary ClintonHillary Diane Rodham ClintonDem targeted by party establishment loses Texas primary Penn to Hewitt: Mueller probe born out of ‘hysteria’ Trump claims a 'spy' on his campaign tried to help 'Crooked Hillary' win MORE for president on Monday, citing her support for gun control and the Black Lives Matter movement.

Sybrina Fulton wrote in an op-ed for CNN that Clinton is "tough enough" to fight against Republican opposition to gun laws.

"As first lady, she advocated for the Brady Bill and convened meetings on school violence," Fulton wrote. "As a senator, she voted to extend the assault weapons ban and against an immunity law that protects irresponsible gun makers and dealers from liability."

"In spending some time with her in person, I also found a mother and a grandmother who truly heard me, and understood the depth of my loss."

In November, Clinton met with Fulton and family members of Michael Brown, the 18-year-old whose shooting death at the hands of a white police officer set off massive protests in Ferguson, Mo.

During their meeting, Fulton said, she and Clinton "talked about Trayvon and other families who have lost a loved one to gun violence. We talked about all of the wishes and hopes we had for their lives. And knowing we can never get them back, we discussed how to prevent more moms from losing their sons to gun violence."

"Clinton will uphold President Obama's recent executive actions, and then she'll go even further. Her plan focuses on reforms that would help keep more guns out of the hands of criminals," she added.
