Donald Trump's White House has a growing sinkhole -- as of this past weekend, it has been growing on the north lawn, Voice of America reporter Steve Herman observed, just near the press briefing room. A second sinkhole has opened up right next to it. Sinkholes in DC forced two residents to abandon their homes in March, and swallowed up a school bus last year. This is the first report of one on the White House lawn. Parts of the city of Washington, DC, are literally built on a swamp. Could the swamp be draining itself?
