Trump personally involved in quest to find National Parks staffer who retweeted image of his sparse inauguration crowd

Thin-skinned from the outset and to the end.

Newly inaugurated President Donald Trump was "directly involved" in the search for the person who, using the official National Park Service account, retweeted side-by-side comparisons of the crowds at Trump's Jan. 20 inauguration ceremony and former President Barack Obama's 2009 ceremony, CBS News has confirmed.

The retweet was deleted soon after it was posted and the Twitter accounts of the National Park Service and other U.S. Interior Department agencies were briefly shut down… "Obviously, this has become a very sensitive issue, especially since the President has gotten directly involved and contacted Acting Director Mike Reynolds concerned about one of the images that was retweeted," wrote Tim Cash, Chief of Digital Strategy at the National Park Service in a Jan. 21 email to Shaun Cavanaugh, the agency's Chief Information Security Officer.
