Washington: House Speaker Nancy Pelosi on Friday cancelled her plans to travel by commercial plane to visit US troops in Afghanistan, saying President Donald Trump had caused a security risk by talking about the trip. It was the latest twist in what has become a Washington game of brinkmanship between Pelosi and Trump, playing out against the stalled negotiations over how to end the partial government shutdown.

Earlier in the week, Pelosi had asked Trump to reschedule his State of the Union address, citing security issues at a time when the Homeland Security Department and other agencies remain unfunded. Trump responded by cancelling the military plane that was to have carried Pelosi and a congressional delegation to Afghanistan on the previously undisclosed troop visit. Trump suggested she travel by commercial plane instead.
