New Delhi, Sept. 10 -- US President Donald Trump's departure for his Republican midterm convention in Dallas, Texas, was unexpectedly delayed after the emergency slide on the Qatari-gifted jet used as Air Force One was deployed.

Trump arrived at Joint Base Andrews by helicopter on Wednesday. He was forced to remain on board for around 20 minutes as the inflatable slide remained deployed near the front of the plane, Bloomberg reported.

He had to wait in his helicopter before being able to board the plane following the incident. Workers on the ground eventually removed the slide, allowing Trump to get underway.
