The White House said that it is still in the "listening phase" on developing gun safety measures and is not yet ready to take legislative action. "The president is proposing ideas -- he's listening right now," White House deputy press secretary Raj Shah told reporters Thursday during the White House press briefing.
Calls for gun control measures have been ramping up after the Parkland high schoolthat left 17 teenagers dead last week. In response, the Trump administration has been weighing plans to curb gun violence in the United States.
Earlier Thursday, President Trump suggested that teachers who are "adept at guns" could receive a bonus for their training in an effort to keep schools safe from armed shooters. Shah reiterated that the president favors training and arming up to 40 percent of school employees. Those teachers, coaches, custodians and administrators carrying concealed weapons would be eligible for bonuses. But who would pay for these measures is unclear.
Arming about 20 percent of teachers adds up to about 700,000 people.
"When you have a horrific shooting like you had last week and some other school shootings that we've seen - these horrible tragedies - what we think and don't think is practical can change," Shah said.
The only daylight between the White House and NRA appears to be on an age limit for semi-automatic gun purchases. The president supports a minimum age of 21, while the NRA opposes that limitation. Mr. Trump spoke with NRA political chief Chris Cox this weekend.
Shah also told reporters the Trump White House will emphasize mental illness in re-assessing background check protocols.
Mr. Trump is not considering a blanket ban on assault weapons, something he supported before running for office.
In a meeting earlier Thursday, the president said he opposed active shooter drills in schools. Shah clarified that the president thinks the name "active shooter drill" is too frightening for children and should be changed. "Safety drills" would be more appropriate, Shah clarified.
Shah said the president would provide political cover for incumbent Republicans who back his firearms proposals if a primary challenger backed by the NRA decides to run against the incumbent.
