US Vice President Mike Pence has ruled out using the 25th Amendment to remove President Donald Trump from office.

In a letter to House speaker Nancy Pelosi, Mr Pence said the mechanism should not be used “as a means of punishment or usurpation” and reserved for cases of medical or mental incapacitation.
