Government shutdown: Trump blocks Pelosi's trip in State of the Union spat as State Department calls in workers

Donald Trump has escalated his spat with House Speaker Nancy Pelosi over a possible delay to the annual State of the Union address by cancelling her upcoming trip to Belgium, Egypt and Afghanistan.

The White House postponed Ms Pelosi's ability to use military aircraft, which is Mr Trump's perogative as commander-in-chief. It comes a day after Ms Pelosi asked Mr Trump to delay the annual State of the Union address. Both blamed the partial government shutdown.

The episode shows how neither side appear close to backing down over the border wall funding issue that sparked the government closure now into its 27th day.
