Donald Trump got into a nasty confrontation with a reporter on the White House lawn Monday.

In a brief meeting with the media prior to his departure for a pair of campaign rallies in Mississippi on Monday evening, Trump selected a reporter who asked him about a tweet in which he claimed that his administration’s child separation policy is the same as former President Barack Obama‘s.

“You said your policy at the border was the same as the Obama administration’s. It wasn’t,” said the reporter.

“Obama had a separation policy,” Trump replied. “We all had the same policy.”

“Sir, it was different — you decided to prosecute everyone at the border,” the reporter responded.

The reporter was CBS News correspondent Paula Reid, according to CNN media reporter Brian Stelter.

Past administrations did not have the same policy as the Trump administration, which has prosecuted all individuals who crossed the border illegally, resulting in thousands of families being separated at the border, more than in previous administrations.

The exchange between Trump and Reid came after the president on Sunday slammed “60 Minutes” over its report on his administration’s “zero tolerance” policy that resulted in families being separated at the border.

.@60Minutes did a phony story about child separation when they know we had the exact same policy as the Obama Administration. In fact a picture of children in jails was used by other Fake Media to show how bad (cruel) we are, but it was in 2014 during O years. Obama separated….

….children from parents, as did Bush etc., because that is the policy and law. I tried to keep them together but the problem is, when you do that, vast numbers of additional people storm the Border. So with Obama seperation is fine, but with Trump it’s not. Fake 60 Minutes!
