Jan. 10 (UPI) -- A Capitol Police officer who responded to the siege on the Capitol building by supporters of President Donald Trump on Wednesday died while off duty on Saturday, the U.S. Capitol Police said.
Officer Howard Liebengood, 51, who was assigned to the Senate Division and had been with the department since April 2005, died while off duty three days after the riot that saw supporters of the president make their way inside the Capitol building as Congress was certifying the results of November's presidential election.
The cause of Liebengood's death was not immediately released.
"We are reeling from the death of Officer Liebengood," Gus Papathanasiou, the chairman of Liebengood's police union, said. "Every Capitol Police officer puts the security of others before their own safety and Officer Liebengood was an example of the selfless service that is the hallmark of USCP. This is a tragic day."
Liebengood was a constituent of Rep. Jennifer Wexton, D-Va., who mourned his death online.
"I'm deeply saddened to learn about the death of USCP Officer Howard Liebengood," she said via Twitter. "My heart breaks for his family, his loved ones & our community."
John Kerry, former secretary of state and former Democratic senator for Massachusetts, called the deaths of the two officers "a tragic loss," stating he was familiar with Liebengood from his time at the Capitol.
"Howie always had a smile on his fact, but he also showed great care for the safety of the young staff who worked behind our office doors," he said in a statement. "A tragic loss of two patriots who spent their careers protecting the halls of democracy."
One woman, identified as Ashli Babbitt, was also shot and killed by authorities at the Capitol during the riot. Three others identified as Rosanne Boyland, Benjamin Philip and Kevin Greeson also died due to medical emergencies on Capitol grounds.
In the aftermath of the riot, dozens of people have been charged with crimes and the FBI has released a slew of photos seeking the public's help in identifying those involved in breaching the Capitol building.
Late Sunday, the Justice Department announced two men seen in photos of the Capitol building siege wearing tactical and paramilitary gear and holding zip tie restraints known as flex cuffs have been arrested.
In a statement, federal prosecutors said Larry Rendell Brock, of Texas, was arrested Sunday in his home state and charged with one count of knowingly entering a restricted building without lawful authority and one count of violent entry and disorderly conduct conduct on Capitol grounds.
Brock was seen in photos wearing green tactical gear and holding white zip tie restraints in the Senate chamber, and was identified last week by The New Yorker, who said he was a retired lieutenant colonel of the Air Force.
Munchel was arrested in Tennessee Sunday and charged with one count of knowingly entering a restricted building and one count of violent entry and disorderly conduct on Capitol grounds.
Munchel was also seen in photographs in the Senate chambers, wearing black tactical gear and holding several zip tie restraints. He also had "an item in a holster on his right hip" and a cell phone mounted to his chest with the camera facing outward," the Justice Department said.
At least 25 domestic terrorism cases have been opened, Rep. Jason Crow, D-Colo., said in a summary of a conversation he had with Secretary of the Army Ryan McCarthy.
The summary states that weapons, explosives and zip ties recovered by authorities at the scene "suggests a great disaster was narrowly averted," and that the Department of Defense "is aware of further possible treats posed by would-be terrorists in the days up to and including Inauguration Day."
The police department's website states Pittman was named acting chief by the Capitol Police Board on Friday.
Her alma mater Morgan State University, which she graduated from in 1999, said in a statement that she is the first woman and first Black person to hold the position.
Sund resigned last week amid calls for him to do so over the failure to prevent Trump's supporters from entering the Capitol building.
On Saturday, President Donald Trump's Twitter account was permanently suspended citing "the risk of further incitement of violence" after several of his tweets during the insurrection were flagged and later removed and his account was temporarily suspended for 12 hours.
That night, Amazon's cloud-computing unit, Amazon Web Services, informed the social media site Parler that it will no longer provide cloud services to the company beginning at 11:59 p.m. PT on Sunday, CNBC reported.
In an email to Parler's Chief Policy Officer Amy Peikoff, Amazon said the platform violated AWS' terms of service by continuing to host "violent content."
"AWS provides technology and services to customers across the political spectrum and we continue to respect Parler's right to determine for itself what content it will allow on its site," the company said in an email to Parler. "However, we cannot provide services to a customer that is unable to effectively identify and remove content that encourages or incites violence against others."
Google and Apple removed the Parler app from their respective app stores over the weekend but users were still able to access the service online or on their devices if they had already downloaded the app. Unless it is able to find a new host, Parler will become unavailable as soon as the Amazon decision goes into effect.
Following the insurrection at the Capitol and amid calls for him to resign or be removed from office in his final days of presidency, Trump is set to visit Texas' Rio Grande Valley on Tuesday.
Although the White House did not provide details of Trump's visit it follows the Department of Homeland Security's announcement that 450 miles of border fencing had been completed during his administration.
Trump's only in-person public appearance since the riot came on Thursday when he awarded pro golfers Annika Sorenstam, Gary Player and Babe Didrikson Zaharias with the Presidential Medal of Freedom on Thursday.
