Arizona Democratic Rep. Raúl Grijalva is nervous.

Last week, the chairman of the House Natural Resources Committee tested positive for COVID-19 in the latest outbreak on Capitol Hill.

And although Grijalva is asymptomatic, he’s worried because he’s 72 years old and an admitted on-and-off smoker.

“You get scared, your family gets scared,” he said from his D.C. home, where he is now quarantining. “If you’re not afraid of this disease, there’s something fundamentally wrong.”

In a matter of one week, three members of Congress have tested positive for the coronavirus illness: Grijalva, Texas Republican Rep. Louie Gohmert and Illinois Republican Rep. Rodney Davis. Gohmert and Davis also said they are asymptomatic.

The latest outbreak is a reminder of the risks for Capitol Hill, as members continue to meet in an attempt to negotiate a new wave of aid to address the coronavirus. Unlike regular, widespread testing programs at workplaces from the White House to the NBA, Congress is going without.

“It’s unbelievable that six months into a pandemic, we don’t have a testing infrastructure that lets us protect members of Congress,” said Dr. Ashish Jha, director of Harvard Global Health Institute.

So far, Congress has seen about 100 cases among its members and workers, including more than a dozen lawmakers. And last month, Florida Republican Rep. Vern Buchanan said his longtime staffer, Gary Tibbetts, had succumbed to the illness.

Davis, a key advocate who has called for widespread COVID-19 testing on Capitol Hill, said on Wednesday he sought a test after noticing he had a slightly elevated temperature. His wife, a cancer survivor, and staff, have since tested negative.

“My staff and I take COVID-19 very seriously. My wife is a nurse and a cancer survivor, which puts her in an at-risk category like so many Americans,” Davis said. “My office and I have always followed and will continue to follow CDC guidelines, use social distancing, and wear masks or face coverings when social distancing cannot be maintained.”

Grijalva himself tested positive last Friday, just days after Gohmert, a member of his Natural Resources committee did as well. A White House screening caught Gohmert’s diagnosis a week ago Wednesday — a day after he sat by Grijalva during a committee hearing.

Gohmert, who has been known to dismiss masks and other precautions for the pandemic, returned to his Capitol office after his test. He was attempting to travel with President Trump for a trip to Texas, but that was cancelled as a result.

The Capitol’s Office of the Attending Physician, a small, on-campus doctor’s office, has advised a series of precautions for members and workers, including mask wearing and social distancing. However, in light of Gohmert’s case, House Speaker Nancy Pelosi instituted a new mask mandate that will allow the forcible removal of a member by U.S. Capitol Police if they don’t comply.

Pelosi says the Capitol still isn’t in a position to institute widespread testing because there’s still equipment shortages making it difficult to test its more than 500 lawmakers and workforce of 20,000. Those that do have widespread testing programs in place, such as pro sports organizations, face their own controversy for gaining access. Some experts including Jha say national testing levels of about 5 million tests per week now should be closer to 30 million.

“There are many people in the country who should be tested, should have access in order to quantify the problem, but also to trace and to treat so that people don’t die,” Pelosi recently told reporters. “And I don’t think it’s a good idea for members of the Congress to say, ‘we should have it but maybe not necessarily the people who work here at the expense of others.'”

In May, Pelosi and the Senate’s top Republican, Majority Leader Mitch McConnell, issued a joint statement turning down the Trump administration’s one-time offer of 1,000 Abbott Laboratories rapid tests — which was considered a small drop in the bucket, many say. At the time, Pelosi and McConnell said Congress shouldn’t cut ahead of frontline workers and others in dire need of tests, which were more scarce at the time.

Also, the Abbott tests remain a challenge to scale up for larger workforces like the Capitol and are more suitable for smaller groups such as the White House, experts say.

However, Jha says Congress should instead be testing its members and employees weekly or more through other options.

“If they don’t, to me, that, to be perfectly honest, is a travesty,” Jha says.

Jha said the Capitol could use newer, so-called antigen tests. Preferably, about 6,000 could be tested daily, since antigen tests are more accessible today, can be scaled for larger workforces and can provide results within minutes.

Such antigen tests have lower sensitivity levels than the more traditional polymerase chain reaction, or PCR, tests, Jha notes. However, when used regularly and frequently to test a certain population, there’s better odds of catching an active case, he argues. In some cases, PCR tests, while more accurate, can also face longer delays for results.

A congressional aide told NPR that by this summer, the Capitol’s Office of the Attending Physician could only conduct about a dozen or so PCR tests a week. And that falls woefully short of the Capitol’s needs, experts argue.

In May, House Republicans, led in part by Davis, also pitched another plan to partner with the military to test about 6,000 or so a week on Capitol Hill. But that also may not be enough, experts say.

However, Jha says a larger testing plan is also a matter of prioritizing Congress. With national tests at a higher level now than just a few months ago, the Capitol is in a better position to install such a program, Jha argues.

“I just think Congress needs to be a priority,” he said. “A lot of older members, it’s high risk and, also, they are the U.S. Congress. This is a really important moment for Congress to be able to be protected.”

When Grijalva first learned of his results, he admits he was angry, and then asked questions of “why me?” And while he says he can’t blame Gohmert directly, he is sure he caught the illness at the Capitol.

“I’ve been doing everything right. I got masks, I got shields, I got gloves, which goes to the point of how insidious this this virus is,” Grijalva said.

The father of three daughters, and grandfather to five children, says his family reacted with their own fear — and anger. From Arizona, his family has sent him a round of herbal treatments, vitamins, a new thermometer and a blood oxygen sensor.

And they’re checking on him frequently.

“I said, ‘I’m not supposed to stress. Quit calling me every 20 minutes,'” he says laughingly.

But he says he is continuing to do well. And he’s hoping he clears this week without symptoms, which he was told is the critical window to escape any serious concerns of the illness.

Meanwhile, he’s re-learning a lesson, and he hopes any of his colleagues like Gohmert, who have at times dismissed precautions, will as well.

“This pandemic doesn’t care what your party affiliation or your political ideology might be,” Grijalva said. “It does not care.”
