The Secret Service and US federal law enforcement agencies are spending the final days of the Trump administration bracing for a possible violent assault against the Jan. 20 inauguration, launching a security mobilisation that will be unlike any in modern US history.
On Wednesday, the Secret Service will take command of security preparations at the US Capitol and other federal buildings, backed by as many as 15,000 National Guard troops, thousands of police and tactical officers, and layers of 2.4-metre-tall steel fencing.
