Conservation groups have loudly criticized the administration for leaving National Park Service sites open without much of the staff to maintain them, clean them and keep parkgoers safe.

The Obama administration closed parks during the 2013 shutdown and faced criticism from Republicans, who said the president was using parks as a bargaining chip with Congress.
