CNN chief White House correspondent Jim Acosta accused White House press aides on Tuesday of trying to “drown out” his questions for President Trump by shouting when he tried to ask them.

In a video of a meeting between Trump and President Nursultan Nazarbayev of Kazakhstan, Acosta can be heard asking Trump questions while press aides are heard repeatedly saying, “thank you, Jim,” and attempting to wrap up questions from the press. 

Acosta in a series of tweets said it was a deliberate attempt to stop him from asking the president questions.

“As I attempted to ask questions in Roosevelt Room of Trump, WH press aides shouted in my face to drown out my questions,” Acosta tweeted. “I have never encountered that before.”

In another tweet, Acosta said the incident reminded him of “something I would see in a different country. … Certainly not in the U.S.”

What occurred reminded me of something I would see in a different country. Certainly not at the WH. Certainly not in the U.S. https://t.co/hV6vPRe0p2

While Trump met with Nazarbayev, Acosta, standing with other reporters, asked why the president said last week that he wanted more immigrants to come to the U.S. from Norway. Trump replied that he wants “them to come in from everywhere.”

But, according to Acosta, when he tried to follow up on that question, Trump ordered him to get “out.” Video of the exchange shows Trump pointing his finger and saying, “out.”

When I tried to follow up on this in the Oval Office, Trump told me to get “out.” We then went to the Roosevelt Room where WH aides obstructed us from asking questions. https://t.co/vuEIv1jvso

This was the first time I’ve seen @realDonaldTrump as @POTUS point a finger and say “out” while reporters were attempting to ask questions. https://t.co/kAbUBPQoj6

Acosta’s questions came after Trump reportedly asked during an Oval Office meeting last week why the U.S. admits immigrants from “shithole countries,” and insisted that more immigrants come from countries such as Norway.
