Obama administration did it.

So in net effect, there was no true moratorium as DOD continued to fund it.

Today, the White House Office of Science and Technology Policy (OSTP) is releasing "Recommended Policy Guidance for Departmental Development of Review Mechanisms for Potential Pandemic Pathogen Care and Oversight (P3CO)." Adoption of these recommendations will satisfy the requirements for lifting the current moratorium on certain life sciences research that could enhance a pathogen's virulence and/or transmissibility to produce a potential pandemic pathogen (an enhanced PPP).
Issuance of this policy guidance concludes the deliberative process launched in October 2014 by OSTP and the Department of Health and Human Services (HHS). At that time, OSTP and HHS asked the National Science Advisory Board for Biosecurity (NSABB), as informed by feedback from the National Research Council of the National Academy of Sciences, to provide recommendations to help shape the development and adoption of a new United States Government policy governing the funding and conduct of this category of research. While NSABB deliberated, such projects were placed on pause.
In May 2016, after thorough deliberation and extensive input from domestic and international stakeholders, the NSABB issued its recommendations. NSABB's central finding was that studies that are expected to enhance PPP have potential benefits to public health but also entail significant risks. NSABB recommended that such studies warranted additional scrutiny prior to being funded. NSABB further recommended a Department-level, multi-disciplinary review and ongoing Federal and institutional oversight for this category of research. The recommended policy guidance that OSTP is issuing today will implement this approach.

An even larger backstory. Eleven Days before leaving office President Obama's administration re-authorized funding for the creation of biological weapons using SARS viruses. However, essentially this re-authorization was only kickstarting funding within the U.S. because the funding of weaponization of SARS-CoV-2 never actually stopped in 2014. The media reporting on this is misleading, if not downright false.
In the original pdf guidance for the 2014 research pause of into weaponization of SARS viruses there was a footnote that everyone seems to have missed

Quote:
This exception essentially permitted the Pentagon to continue funding the creation of SARS as a biological weapon in Wuhan, China, under the auspices of national security. Which is exactly what the defense department did: "Grants from the Pentagon included $6,491,025 from the Defense Threat Reduction Agency (DTRA) from 2017 to 2020"
LinkQuote:
October 17, 2014 U.S. funding of SARS to create a biological weapon was paused due to the extreme risk of a pandemic. However, the pause allowed agencies within the U.S. government to continue funding if they determined "the research is urgently necessary to protect the public health or national security."
2014 through 2020 the Pentagon continued funding research in Wuhan, China. Fear of discovery would explain why many top officials in the U.S. Defense Department were against the Trump administration [with increased severity after the COVID pandemic began].

January 9, 2017 [Four Days after the Susan Rice oval office meeting with Obama, Biden, Comey, et al] The Obama Administration re-authorizes funding for the creation of SARS biological weapons. "Adoption of these recommendations will satisfy the requirements for lifting the current moratorium on certain life sciences research that could enhance a pathogen's virulence and/or transmissibility to produce a potential pandemic pathogen (an enhanced PPP)."
So in net effect, there was no true moratorium as DOD continued to fund it.
