Thursday's session follows one on Wednesday in which the president heard emotional pleas from students and parents affected by the fatal shooting of 17 people at a Parkland, Florida, high school.
At the Wednesday meeting, billed as a "listening session", Trump also promised "very strong" background checks on gun owners. But in the aftermath of yet another mass school shooting, there are deep divisions, from President Donald Trump to educators, parents and school security officers, about whether teachers should be armed.
Gunman Nikolas Cruz, 19, killed 14 students and three school workers at Marjory Stoneman Douglas High in Parkland, Florida with an AR-15 assault rifle.
"I'm not here to tell all teachers that they have to carry a gun", said Hansen, the Utah teacher, who's from Salt Lake City.
On Thursday morning however, he clarified his remarks on Twitter by claiming that he never said "give teachers guns" unless they happen to be "gun adept" or military trained teachers or coaches, which still sounds like "give teachers guns".
The President also said he would be in favor of raising the minimum age for buying certain guns to 21, and expressed hope Congress would act on the issue.
The president advocated for the legalization of concealed carry on the campaign trail and said that he would "get rid of gun-free zones in schools" on his "first day in office".
Mr Trump is also supportive of the idea to arm more teachers within schools. Highly trained, gun adept, teachers/coaches would solve the problem instantly, before police arrive.
"Instead of advertising the school has no guns, we are gun free, do the opposite", he said.
"Shot nine times", he said.
Upon closer review, however, something arguably more dumbfounding than the president's suggestion that handguns become a teacher supply was what he held in his hand as he put forth that idea.
Samuel Zeif, who lost a close friend at Stoneman Douglas last Wednesday, said it was important to "be strong for the fallen who don't have a voice to speak anymore". "I can't get on a plane with a bottle of water, but we leave some animal to walk into a school and shoot our children".
"We're going to cover every aspect of it", Trump said. Do you think giving teachers guns will help stop future school shootings?
