"I would like to say to Mr. President Donald Trump...he said he wants to 'Make America Great Again.' We want him to say that he wants Americans to be safe again," Arco said.

"The Congress, somebody needs to do something fast before another victim, another family, another kid [is left] without a dad," she added. "That's uncalled for. Please do something."

Trump, who has indicated support for expanding background check requirements for gun purchases in recent weeks following other mass shootings, said that Saturday's shooting in Odessa "hasn't changed anything" on Capitol Hill related to discussions about gun control.

“We're looking at the same things,” Trump said on Sunday. “It really hasn't changed anything."

“A lot of people are talking about it, and that’s irrespective of what happened yesterday in Texas,” he added.

Democrats are hoping the Senate will take up a bill that would expand background checks to all gun purchases, closing the so-called "gun show loophole."

ABC News reported Tuesday that the Odessa gunman had purchased his through a private gun sale after failing an earlier background check.

Trump has previously voiced support for expanding background checks before backing away from the issue after conferring with congressional Republicans and gun-rights advocates.
