Washington | The first terrorism threat on US soil since the fall of Kabul, and less than a month from the 20th anniversary of the September 11 terrorist attacks, has turned out to be from a North Carolina man demanding that President Joe Biden resign.

The chosen spot for this “yeehawdist” (slang for American militant) and his utility truck, which he claimed was loaded with ammonium nitrate, was outside Washington’s Capitol building – and about 200 metres from an apartment I decided to vacate a few weeks ago.
