Story highlights Trump has been consumed by negative comments about the size of the crowd at his inauguration 
 
 Aerial photos have indicated that Obama's first inauguration attracted a larger crowd 
 
 Washington (CNN) President Donald Trump, angered over a National Park Service retweet comparing his inaugural crowd size to Barack Obama's in 2009, called the acting director of the National Park Service on Saturday to complain, two sources with knowledge of the call told CNN. White House deputy press secretary Sarah Huckabee Sanders said the call simply demonstrated that Trump’s management style is to be “so accessible, and constantly in touch.” 
 
 “He’s not somebody who sits around and waits. Sanders said the call proves Trump "is so engaged, he is so involved and when he sees a problem, he takes action to fix it."
– President Trump may not have had the biggest inauguration crowd in history, but he may have made a bigger fuss about media coverage of it than any of his predecessors. Sources tell the Washington Post and CNN that on Saturday morning—the first morning of his presidency—Trump contacted Michael T. Reynolds, the National Park Service's acting director, to demand more photos of the crowd on the National Mall. Reynolds, who has worked for the service for 30 years, was "taken aback" by the request, but he sent some aerial photos to Trump, according to the Post's sources. The photos did not, however, provide proof of Trump's claim that more than a million people had gathered to watch his inauguration. Reynolds and the NPS have declined to comment, but insiders say Trump also expressed anger over an NPS tweet comparing his crowd to Obama's, which apparently led to an order for all Interior Department accounts to stop tweeting. White House deputy press secretary Sarah Huckabee Sanders confirmed that Trump contacted the NPS. She said the call demonstrated the president is "so accessible, and constantly in touch." "He's not somebody who sits around and waits. He takes action and gets things done," she said. "That's one of the reasons that he is president today, and Hillary Clinton isn't." (Trump was still talking about the size of his inaugural crowd on Wednesday, when he gave his first interview as president.)
