WASHINGTON — Not two weeks ago, President Donald Trump wagged his finger at a Republican senator and scolded him for being “afraid of the NRA,” declaring that he would stand up to the powerful gun lobby and finally get results on quelling gun violence following last month’s Florida school shooting.

On Monday, Trump struck a very different tone as he backpedaled from his earlier demands for sweeping reforms and bowed to Washington reality. The president, who recently advocated increasing the minimum age to purchase an assault weapon to 21, tweeted that he’s “watching court cases and rulings” on the issue, adding that there is “not much political support (to put it mildly).”

Over the weekend, the White House released a limited plan to combat school shootings that leaves the question of arming teachers to states and local communities and sends the age issue to a commission for review. Just two days earlier, Trump had mocked commissions as something of a dead end while talking about the opioid epidemic. “We can’t just keep setting up blue-ribbon committees,” he said, adding that all they do is “talk, talk, talk.”

Seventeen people were killed in last month’s shooting at Marjory Stoneman Douglas High School in Parkland, Florida, prompting a national conversation about gun laws, fierce advocacy for stronger gun control from surviving students and, initially, a move from Trump to buck his allies at the National Rifle Association.

In a televised meeting with lawmakers on Feb. 28, Trump praised members of the gun lobby as “great patriots,” but declared “that doesn’t mean we have to agree on everything. It doesn’t make sense that I have to wait until I’m 21 to get a handgun, but I can get this weapon at 18.”
