The President said that he had spoken with the Texas and OH governors, and with US Attorney General William Barr and members of Congress to see what can be done to halt gun violence in the US, and he added that on Monday he will issue an official statement on the shootings from the White House.
Obama criticized the position of elected officials and members of the public who maintain that stricter gun laws will not stop a person determined to carry out mass violence, saying common sense measures can help prevent some killings and "save some families from heartbreak". Less than a day later there was another mass shooting in Dayton that killed at least nine, while at least 27 others were injured.
But for many critics like O'Rourke, Trump's record speaks louder than the president's latest condemnation of the attacks.
In a national address to the country hours earlier, Trump said, "Now is the time to set destructive partisanship aside - so destructive - and find the courage to answer hatred with unity, devotion, and love". Detectives sought to determine if it was written by the man who was arrested. The White House threatened a presidential veto if those measures passed Congress. But he later retreated, expressing support for modest changes to the federal background check system and for arming teachers.
Accompanied by his wife and First Lady Melania, Trump said that "mental problems" had contributed to the shootings, but he did not respond to reporters' questions about the alleged anti-immigrant manifesto that the suspected El Paso shooter had posted online prior to carrying out the attack on Saturday morning in the Texas city.
In recent weeks, the president has issued racist tweets about four women of color who serve in Congress, and in rallies has spoken of an "invasion" at the southern border.
"The unfortunate part of this. they are finding some form of license in the president who has been using rhetoric. that seems to incite and inflame these extremists", he tells Newsnight. "No other developed nation tolerates the levels of gun violence that we do". The survey was conducted both before and after a mass shooting at two mosques in New Zealand.
Less than a week after the mosque shootings, New Zealand moved to ban "military-style" semi-automatic weapons and high-capacity magazines; similarly, after a mass shooting in 1996, Australia enacted sweeping gun bans within two weeks.
"Mental illness and hatred pulls the trigger, not the gun", he said.
