Update 12:22 p.m. The Georgia-based manufacturer of the assault rifle model used in Tuesday’s mass shooting at Robb Elementary has pulled out of the NRA convention in Houston this weekend, according to a report from the Daily Beast.

Daniel Defense — who designed the DDM4 V7 rifle — was originally slated to host a booth at the George R. Brown Convention Center but now the booth they were assigned to will be occupied by the NRA itself.

The Houston Chronicle previously reported that the Uvalde gunman, Salvador Ramos, purchased two weapons and hundreds of rounds of ammunition in the days immediately after his 18th birthday, which was on May 16. One weapon was the Daniel Defense rifle; the other was a Smith & Wesson MP 15, which retails for about $1,300.

Update 11:39 a.m. Larry Gatlin and Don McLean have both pulled out of their respective performances at the NRA’s annual convention held in Houston, according to The Chronicle’s Joey Guerra.

Gatlin released a statement on the heels of Thursday morning’s news that McLean would not be participating in Saturday’s Grand Ole Night Of Freedom Concert at the George R. Brown Convention Center.

“I pray that the NRA will rethink some of its outdated and ill-thought-out positions regarding firearms in America,” he said, adding he could not “in good conscience” perform and that he is in support of background checks.

The performance lineup still includes Lee Greenwood, Restless Heart’s Larry Stewart, T. Graham Brown, “NRA Life member” Jacob Bryant and Danielle Peck.

Update 11:15 a.m. As negotiations on possible gun reform got underway in the U.S. Senate on Thursday, Majority Leader Chuck Schumer blasted Gov. Greg Abbott as an “absolute fraud,” according to a report from The Chronicle’s Washington correspondent Benjamin Wermund.

Schumer accused Abbott of offering nothing but “empty platitudes about healing and hope” during a press conference in Uvalde on Wednesday.

“This is the same Gov. Abbott who tomorrow — tomorrow — will go speak at the NRA convention in Houston,” Schumer said. “Gov. Abbott, will you ask your MAGA buddies and your NRA pals to put aside their agendas and think of someone other than themselves like you asked the families to do?”

Update 10:20 a.m. Although Uvalde CISD had an extensive security plan in place for moments of crisis, the district’s planning failed to stop 19 children from being shot and killed at Robb Elementary School, according to an article from NBC News.

The district had doubled its security budget in recent years, according to documents, after legislation was passed in the aftermath of the 2018 Santa Fe High School in which eight students and two teachers were killed.

Update 9:15 a.m. Lt. Gov. Dan Patrick appeared on Fox & Friends this morning and spoke on “hardening’ schools” and mental health in the wake of the mass shooting at Robb Elementary School.

“We are a country in the ditch,” Patrick said. “We have violent music, violent rhetoric, everything is anti-everyone. Where are we as a nation? We have people in this nation who want to pull us away from God.”

Patrick also took issue with identifying some people with mental health issues as “loners,” saying some are not really alone but connect via the Internet with others who would praise their violent acts.

“They are on the Internet all day long where they play their violent video games where they kill hundreds of people a day.”

Update 7:17 a.m. Late-night talk show host Jimmy Kimmel opened his show without an audience Wednesday evening, speaking to the camera uninterrupted for about 10 minutes in an impassioned segment on Uvalde and gun reform.

Kimmel initially got choked up when mentioning the “little boys and girls whose lives have been ended.” He then took aim at Republican lawmakers, Fox News, Sen. Ted Cruz and others over the current state of U.S. gun laws.

“If your solution to children being massacred is armed guards, you haven’t been paying attention to what’s going on,” he said. “There was an armed guard in Buffalo. There was an armed guard in Parkland. There was an armed guard in Uvalde.”

Update 6:15 a.m. As the tragedy unfolded at Robb Elementary School, a crowd of frustrated onlookers were urging police to charge in and stop the violence, the Associated Press reported.

“Let’s just rush in because the cops aren’t doing anything like they are supposed to,” said Javier Cazares, whose fourth grade daughter, Jaclyn, was killed in the attack.
