Trump campaign starts selling 2020 face masks

• The Trump campaign also said face masks were optional at its rally in Tulsa, Okla., where thousands of people gathered.

Between the lines per Axios' Margaret Talev: This gives Trump a prop to try to take credit for the widespread bipartisan use of masks that began before he was advocating for it.

• To be sure, mask use among his base increased once he belatedly got on board — the campaign figures if his supporters are going to wear a mask anyway it might as well be a billboard for him, and a campaign contribution. 

The other side: The Biden campaign first started selling face masks in late May, CNN reports.

• The former vice president has taken a different approach to face masks than Trump, calling on governors to issue a three-month mandatory outdoor mask mandate.
