Washington (CNN) A State Department official who quit after he says the White House blocked his written testimony on climate change from being delivered to Congress says the Trump administration is "undercutting evidence that contradicts its policy positions."

"I take great pride in the many positive and productive interactions I had with senior officials in my 30 months in the Trump administration," Rod Schoonover wrote in a New York Times op-ed published Tuesday. "But the decision to block the written testimony is another example of a well-established pattern in the Trump administration of undercutting evidence that contradicts its policy positions."

Last month, the White House office of Legislative Affairs blocked Schoonover, who worked as an intelligence analyst for the department, from submitting written testimony to the House Intelligence Committee that offered major warnings "on the national security implications of climate change," according to a report from The Washington Post citing several senior administration officials.

The written testimony Schoonover was prepared to submit, which warned that human-caused climate change could be "possibly catastrophic," according to the Post, stood in marked contrast to the generally dismissive tone President Donald Trump has taken towards climate change and to recent remarks from Secretary of State Mike Pompeo.

The White House did not immediately respond to CNN's request for comment on Tuesday.
