A bipartisan group of senators on the Health, Education, Labor, and Pensions (HELP) Committee called out public health officials’ response to the monkeypox outbreak, with Republicans suggesting that they would not support increased funding for several federal agencies.

Centers for Disease Control and Prevention (CDC) director Dr. Rochelle Walensky, White House Chief Medical Advisor Dr. Anthony Fauci, Food and Drug Administration Commissioner Dr. Robert Califf, and Health and Human Services Assistant Secretary Dawn O’Connell testified about the virus for more than two hours. Although all four witnesses expressed optimism about the Biden administration’s monkeypox response, most senators pushed back. The U.S. has reported 22,630 monkeypox cases, according to the CDC, although no people have died due to the virus.

HHS Secretary Xavier Becerra declared a public health emergency for monkeypox on Aug. 4, more than two months after the first case was reported in the U.S., according to CNBC. Republican Indiana Sen. Mike Braun questioned the need for an emergency declaration in the first place, noting the lack of fatalities and the federal government’s historical reluctance to declare emergency status.

“I’m concerned that the public health emergency declarations will not be taken seriously,” Braun said, asking Walensky how the CDC decides to declare public health emergencies.

Walensky cited the “increased number of new cases,” for the decision, noting that the declaration unlocks “increased funding and new resources.”

O’Connell claimed that the emergency declaration sent an “important signal to the community. It aligned with what the WHO did.”

“Ultimately it’s the Secretary’s decision,” she added.

Committee chairwoman Patty Murray of Washington criticized the administration’s failure to ramp up monkeypox vaccine supply, characterizing the public health approach as filled with “serious stumbles.” Public health officials are targeting gay men, who make up 97% of cases, for vaccine outreach. They have also used smallpox vaccines in lieu of monkeypox ones, O’Connell noted. (RELATED: Meet Joe Biden’s Monkeypox Czar—A Gay Doctor In Drag Who Wants To ‘Dismantle Stigma’)

Fauci repeatedly compared monkeypox to HIV/AIDS, and stressed the importance of “avoiding stigma” when discussing the new outbreak. The outgoing head of the National Institute of Allergy and Infectious Disease led the federal government’s HIV/AIDS response in the 1980s. Fauci faced widespread criticism from activists for his handling of that crisis.

Democratic Minnesota Sen. Tina Smith noted vaccine distribution issues spurred on by the use of separate allocation systems for COVID-19 and monkeypox.

“This is happening at a time when challenges are falling on public health departments and staff that are exhausted and burned out after the last two-and-a-half years of responding to COVID-19,” she said. “It’s sort of exacerbated, I think by the department having trouble tracking shipments of vaccines through VTrckS, and monkeypox vaccines showing up unexpectedly.”

Walensky called on the senators to vote for President Joe Biden’s budget proposal, which would allocate $4.5 billion to public health agencies for monkeypox response, as well as $22.4 billion for COVID-19 response. The CDC director added that she expects “monkeypox to remain a global threat.”

Republicans expressed skepticism of the proposal, with Louisiana Sen. Bill Cassidy and committee ranking member Richard Burr of North Carolina noting the CDC’s continued remote work policies.

Burr claimed that public health officials are too focused on blaming each other for the failures to respond to monkeypox, and not addressing the issue at hand.

“Let’s quit blaming everybody, and actually start showing some leadership,” he said. “It’s a question of leadership. It’s a question of focus.”
