President Donald Trump's departure was delayed due to an issue with a new presidential aircraft. An emergency slide deployed on the plane, which was a gift from Qatar. The president suggested that the deployment was intentional, stating it was part of a check.

The incident occurred as Trump was preparing to leave for a GOP convention. He had arrived at Joint Base Andrews aboard Marine One. After the slide deployed, Trump remained on Marine One for over 20 minutes.

Further details about the incident are available from the source, including the president's comments to reporters on the tarmac.
