WASHINGTON — On his first full day in office, President Donald Trump called the acting director of the National Park Service to dispute widely circulated photos of Trump’s inauguration.

Trump personally ordered park service head Michael Reynolds to produce additional photographs of the previous day’s crowds on the National Mall, The Washington Post reported. The president believed that the photos might prove that the news media had lied in reporting that attendance had been no better than average, the newspaper said.

The Post reported that Reynolds forwarded additional photos to the White House as requested.

Photos taken that day made clear that crowds didn’t extend to the Lincoln Memorial as Trump later asserted and that his claim of 1 million to 1.5 million people in attendance was wrong.

A spokesman for the park service confirmed the call Thursday night but declined to reveal details of the conversation.

Trump also expressed anger over a retweet sent from the park service’s account, in which side-by-side photographs showed far fewer people at his swearing-in than had shown up to see President Barack Obama’s inauguration in 2009, the Post reported.
