WASHINGTON — Hide the swamp. The Trump administration has decided not to let the public know who's visiting the White House by refusing to release its visitor logs, officials announced Friday. That's a major change from the last administration. President Obama's team voluntarily disclosed the comings and goings of most visitors to the White House grounds, and the Obama administration released more than 6 million records during his presidency, posting them online for the public's perusal. Trump officials explained the change as a national security issue, though the Obama administration never had that concern.
