The Justice Department drafted legislation to speed up the death penalty for mass shooters, according to Vice President Mike Pence’s chief of staff Marc Short, who said the vice president is coordinating with Attorney General William Barr.

Short, who made this revelation while talking to reporters on Air Force Two on a Labor Day flight to Europe, said the vice president’s office has been working with the attorney’s general’s team on the issue.

The proposal to expedite capital punishment for those found guilty of mass murder would be a part of the White House’s eventual legislative package proposal to Congress when lawmakers return from their August recess to debate gun laws in the wake of a number of recent mass shootings.

The Justice Department did not immediately respond to the Washington Examiner's request for comment.

Seth Ator, 36, fired upon police after being pulled over and led them on a chase, which included stealing a mail truck, as he carried out a shooting spree on Saturday, killing at least seven people and wounding many more in Midland and Odessa, Texas, before he was killed by police.

Connor Betts, 24, shot and killed nine people including his sister and wounded more than two dozen others before he was shot and killed by police in the early hours of the morning in a mass shooting in Dayton’s Oregon District, a popular bar and restaurant scene, earlier in August.

Patrick Crusius, 21, posted a racist and anti-Hispanic four-page manifesto drawing inspiration from the Christchurch, New Zealand, mosque shootings on 8chan prior to his mass shooting at a Walmart in El Paso, Texas, which took the lives of 22 people the day before the Dayton shooting. Unlike Ator and Betts, Crusius was captured alive.

Jaime Esparza, El Paso County’s district attorney, said Crusius would be charged with murder and that they were pursuing the death penalty. John Bash, the U.S. attorney for the Western District of Texas, said he’d been in close consultation with Barr and that DOJ wanted to bring significant charges against the shooter which could carry a penalty of death. Bash also said DOJ was treating the attack as an act of domestic terrorism.

Following the shootings in El Paso and Dayton in early August, Trump gave a speech where he said he was “directing the Department of Justice to propose legislation ensuring that those who commit hate crimes and mass murders face the death penalty.” Trump said he wanted to ensure that “this capital punishment be delivered quickly, decisively, and without years of needless delay.”

And, in late July, Barr directed the federal government to resume federal executions, beginning with five men convicted of murdering or raping children and the elderly, marking the first federal executions since 2003.
