WHAT TO KNOW TODAY

Trayvon Martin’s mother will run for office to push for gun violence prevention. Sybrina Fulton this past weekend announced her candidacy for Miami-Dade County commissioner. Her son was 17 years old when he was fatally shot as he walked home from a convenience store in 2012. Trayvon’s killer was later acquitted on self-defense grounds. Fulton joins at least two other “Mothers of the Movement” whose bids for office were sparked by the shooting deaths of their sons.

Emails reveal the NRA’s role in the “Second Amendment Sanctuary” movement. In February, the New Mexico Sheriffs’ Association issued a declaration pushing for local officials to pass resolutions prohibiting the enforcement of new gun reform laws. The declaration was crafted in collaboration with the National Rifle Association, according to correspondence obtained by the gun violence prevention group Brady through a public records request.

A House panel voted to decrease funding for an anti-crime program embraced by the Trump administration. Federal dollars for Project Safe Neighborhoods, a George W. Bush-era initiative reinvigorated in March 2017 by then-Attorney General Jeff Sessions, have been cut in the first Justice Department budget approved by the House Oversight Committee since Democrats retook the House.

Three police officers were shot while investigating a domestic disturbance in Alabama. The Sunday night shooting prompted a manhunt that led to the arrest of a 29-year-old military veteran. Authorities said he opened fire on a group of officers responding to a call at a mobile home park in Auburn, killing one and wounding two others. From The Trace archives: A 27-year police veteran explained why domestic disputes are more likely than other scenarios to lead to an officer getting shot.

Pittsburgh will postpone enforcing its new firearm laws until it resolves lawsuits brought by gun groups. A judge on Monday issued a temporary stay against the implementation of bills the Pittsburgh City Council approved in April. The bills, passed six months after 11 people were killed in a hate-fueled gun rampage at a local synagogue, include a ban on the use of certain assault-style weapons and high-capacity magazines. Local gun rights groups allege that the restrictions violate a state law preventing municipalities from regulating firearms.

At least two transgender women were fatally shot in two days. Muhlaysia Booker, 23, made national headlines in April as the victim of a videotaped attack that police investigated as a hate crime. On Saturday morning, she was found shot and killed on a Dallas street. Police said there was no evidence linking her murder to the earlier attack. The next morning in Philadelphia, a 40-year-old trans woman was found shot to death. In a Facebook post, the city’s director of LGBTQ affairs wrote that police had found no evidence that the killing was a hate crime.

A man fatally shot his daughter after mistaking her for an intruder. Nadeja Jermainequa Pressley, 23, was killed early Sunday as she entered her home in Greenville, North Carolina. Context: American gun owners fired at friends, family members, and emergency responders they mistook for intruders almost 50 times between 2015 and 2018, according to a joint Trace/BuzzFeed News investigation last year.

ONE LAST THING

What it’s like to graduate from a school still reeling from a mass shooting. You might suspect that seniors would feel relief to not have to return to hallways now scarred by trauma, but instead of escape, some feel isolation, BuzzFeed found after talking to students who graduated in the immediate wake of four school shootings. “While some might think the first class to graduate after a school shooting would be in the best position to move on from the scenes of such horrors, it’s these students who may be most in danger as they leave the built-in support of the school community,” the site reports. Returning students have each other to lean on; the grads move on, but on their own.
