Retired astronaut Mark Kelly on Wednesday said that President TrumpDonald TrumpTexas announces election audit in four counties after Trump demand Schumer sets Monday showdown on debt ceiling-government funding bill Pennsylvania AG sues to block GOP subpoenas in election probe MORE should be willing to take responsibility for tens of thousands of gun deaths across the United States in 2017 after the president took credit for commercial aviation seeing its safest year on record.

In a tweet, Kelly said that the Transportation Department, the Federal Aviation Administration, NASA and commercial airlines were largely responsible for the industry's safety record in 2017.


"Actually, it's USDOT, FAANews, & NASA —and especially the airlines— who deserve credit for this," Kelly tweeted. "But, if you're going to take credit for zero airline deaths in 2017 then you should take responsibility for the tens of thousands of gun deaths, too."

Kelly's comment came hours after Trump boasted that he had been "very strict" on commercial aviation since taking office, though he did not elaborate on what steps he took to improve airline safety.

Kelly is a staunch advocate for tightening gun control. His wife, former Rep. Gabrielle Giffords (D-Ariz.), was shot and critically injured in 2011. The couple has vocally supported tougher gun laws.
