It was a marked change for both Pence and Abbott, who had trumpeted progress made by Texas and other states in re-opening.
"You flattened the curve here in Texas," Pence said, but that has changed as new cases have gone from a 7-day average of 1,273 on June 1 to a 7-day average of nearly 5,800 cases a day by this weekend.
Pence arrived with a notable change, as he wore a mask by descending the steps of Air Force Two, and then kept it on through his day in Texas.
"Wearing a mask is just a good idea," said the Vice President, who on Friday had not joined in wearing a mask during a news conference with federal health experts in Washington, D.C.
"Wear a mask, wherever it's indicated," Pence added.
On his visit in Texas, Pence went to a large indoor church service - where some people were wearing a mask - but not members of a large church choir, who sang during the services.
Earlier this year, the Centers for Disease Control detailed how a church choir practice had become a superspreading event for the Coronavirus, as a 2.5 hour practice attended by 61 people resulted in two virus deaths.
But when the CDC issued guidelines for church choirs, a CDC warning about church choirs was removed.
