It's safe to assume that U.S. Sen. Dianne Feinstein and President Donald Trump do not agree on most things. But the Democrat lost her composure – in a good way – during a Wednesday meeting with the president about gun control.

The exchange did not take place in an alternate universe, but rather the White House Cabinet Room.

Feinstein (D-Calif.) literally jumped with glee after some of the president's remarks appeared to support her proposed ban on assault weapons.

Here's how things went down: After Sen. Amy Klobuchar (D-Minn.) advocated for expanded background checks to curb domestic violence, Trump said her proposal should be added to a bipartisan gun reform bill sponsored by Sen. Pat Toomey (R-Penn.) and Sen. Joe Manchin (D-W.Va.).

Then he suggested that Feinstein "could add what you have also ... into the bill."

Feinstein seemed to levitate a few inches from her seat as Trump's comment registered. She then looked at Manchin, her face aglow, and quipped, "Joe, are you ready?"

Trump backed her up. "Joe, can you do that? Can you add some of the things?" he asked and offered his "help."

"We're going to get it passed," Trump added.

The convivial moment was not the only unexpected occurrence in the meeting (read The Chronicle's full recap here). In a seemingly left-slanted move, Trump told lawmakers to defy the National Rifle Association to quickly pass a gun safety bill.

"Hey, I'm the biggest fan of the Second Amendment," he said.

"It's time," he said he told the NRA officials. "We have to stop this nonsense."
