President Donald Trump needled his Democratic rival Joe Biden Friday for limiting his campaign appearances to virtual events from the basement of his home in Delaware.

Trump is eager to resume normal campaigning, which has come to a halt amid the coronavirus pandemic. His rallies are a hallmark of his Republican campaign and help energize his base and provide his team with crucial data that will be used to turn out supporters in the fall. Biden, meanwhile, is known for connecting more effectively with people in smaller settings and has struggled with large rallies, something Trump would like to highlight.

Trump made his first trip out of Washington in more than a month this week. He relies on a federal supply of coronavirus tests to maintain a traditional schedule and said he’d be willing to provide Biden with that test as well if that helped resume normal campaign activities.

Trump offered to supply Biden with a rapid COVID-19 testing system. If Biden’s team asked for the tests, Trump said, “We would have it to them today.”

Trump, Vice President Mike Pence and anyone they come into close contact with are now being tested daily for COVID-19 after one of the president’s valets tested positive for the virus this week. On Friday, Trump revealed that Pence’s press secretary, Katie Miller, who is married to senior Trump adviser Stephen Miller, had also tested positive for the coronavirus. The availability of the tests has allowed Trump and Pence to resume a travel schedule and to host business leaders, medical professionals and lawmakers for meetings.

Responding to concerns raised last week by Dr. Brian Monahan, the attending physician of the U.S. Congress, that his office did not have the capacity to test all lawmakers returning to Washington, Trump directed that Congress be provided with three of the testing machines.

But in a rare joint statement, House Speaker Nancy Pelosi and Senate Majority Mitch McConnell rejected Trump’s offer, directing the test kits to first responders and others on the front lines of fighting the spread of the virus.

Biden’s campaign did not respond Friday to inquiries about what the former vice president’s testing protocol has been or whether he’d accept any testing help from the White House. Biden has said he wears a mask around others in his home, including Secret Service agents.
