Donald Trump toured a new medical mask factory without wearing a face covering, despite a sign at the facility making clear they were required.
The US leader visited the factory in Arizona on Tuesday, taking a rare trip out of Washington to visit a state he hopes to win in the November election.
Mr Trump did not wear a mask at the factory, even though workers at the facility did, despite telling reporters at the White House that he would likely do so.
A sign was visible on the president’s tour that read: “Attention: Face Mask Required in this Area Thank You!”
The federal government has encouraged Americans to wear masks to avoid spreading the virus even when not feeling any symptoms of Covid-19, the respiratory disease it causes.
Mr Trump has so far declined to wear a mask himself.
