Top DOE and NASA nominees to testify
The Senate will consider a raft of President Donald Trump’s nominations for leadership positions at the Department of Energy, NASA, and other agencies this week. The Energy and Natural Resources Committee will hold a hearing Thursday on the nominations of National Science Board Chair Darío Gil to be under secretary of energy for science and innovation and attorney Preston Griffith to be a separate under secretary of energy. During the Biden administration, the under secretary for science oversaw the DOE Office of Science and various applied energy R&D offices, while the other under secretary oversaw energy technology demonstration and deployment programs funded through recent infrastructure legislation. However, the Trump administration may rescope these roles. The Armed Services Committee will hold a hearing Tuesday on the nomination of former Rep. Brandon Williams (R-NY) to lead DOE’s National Nuclear Security Administration along with three nominations for Defense Department roles.
NASA administrator nominee Jared Isaacman will testify at a Wednesday hearing by the Senate Commerce, Science, and Transportation Committee. Isaacman is a billionaire tech CEO who has commanded two private orbital missions led by SpaceX. Isaacman has criticized aspects of NASA’s human space exploration programs in recent years, calling the Space Launch System rocket “outrageously expensive.” He has also drawn attention to these high costs in light of NASA’s proposed cuts to the Chandra X-ray observatory, petitioning the agency to fully fund the telescope. Isaacman’s nomination has been praised by various space industry stakeholders while drawing criticism from some conservative groups and activists due to his past donations to Democratic campaigns and the diversity initiatives of companies he has been involved with. Also on Wednesday, the committee is slated to vote on advancing the nomination of Arielle Roth to lead the National Telecommunications and Information Administration. On Thursday, the Banking, Housing, and Urban Affairs Committee will hold a hearing on the nomination of former House CCP Committee staffer Landon Heid to be assistant secretary of commerce for export administration at the Bureau of Industry and Security, which is responsible for developing and implementing export regulations.
Scientists challenge grant terminations in court
Researchers are taking legal action after the National Institutes of Health terminated hundreds of research grants over the last month. Four scientists joined the American Public Health Association and two other organizations in suing NIH, alleging that the reason given for the cancellations — that the research does not support agency priorities — is arbitrary and unjustified and therefore illegal. Furthermore, the lawsuit states NIH exceeded its legal authority by disregarding congressional mandates to fund health disparities research and address the underrepresentation of certain groups in the medical field. The lawsuit aims to restore funding to the impacted researchers and prevent the NIH from continuing to cut awards in this manner, according to a press release from the American Civil Liberties Union.
Litigation against university-specific cuts is also ongoing. Last month, the American Association of University Professors filed a lawsuit on behalf of members who are also faculty at Columbia University, which is poised to lose $400 million in funding, including more than $250 million in NIH grants. The Trump administration has targeted several Ivy League universities for grant cuts, including the University of Pennsylvania, Harvard University, Princeton University, and most recently Brown University.
Senators probe HHS reorganization amid major firings and rehirings
Leaders of the Senate Health Committee called on Health and Human Services Secretary Robert F. Kennedy Jr. to testify on Thursday on his reorganization of the department, which has resulted in more than 10,000 layoffs and reduced the number of HHS divisions from 28 to 15. The senators referred to Kennedy’s moves as a “proposed” reorganization, suggesting they may challenge some of the changes. The layoffs included more than 1,000 staff at the National Institutes of Health, including the removal of four institute directors who were career civil servants. Some of these directors and other laid-off HHS employees were offered reassignments to the Indian Health Service, which would require them to locate to more remote regions of the country.
At one NIH institute, ten principal investigators were fired only to be brought back days later, Science reported. Some were told that a computer or coding error led to their accidental terminations. Kennedy told reporters that he expected 20% of the layoffs across the department would be made in error. “Personnel that should not have been cut were cut. We’re reinstating them. And that was always part of the plan. Part of the DOGE, we talked about this from the beginning, is we’re going to do 80% cuts, but 20% of those are going to have to be reinstated, because we’ll make mistakes,” he said. However, subsequent reporting suggests HHS does not intend to reverse the layoffs to that degree. Meanwhile, the Department of Government Efficiency has directed HHS to cut contract spending by 35% at each of its divisions.
Other departments are now re-offering deferred resignations in advance of reductions in force. Department of Energy employees have until Tuesday to respond to the offer, Department of Interior staff have until Wednesday, and Department of Defense staff have until next Monday.
House examines US-China competition in AI models
The House Science Committee will hold a hearing Tuesday on AI models from the Chinese company DeepSeek, which drew attention early this year when its R1 model performed comparably to U.S.-developed models while apparently being more cost-effective and using less advanced chips. The hearing will explore the state of competition in open-weight AI models, the role that U.S. technology played in the DeepSeek models’ advancement, and the federal role in supporting private sector AI R&D. The witnesses are Adam Thierer, a senior fellow at the R Street Institute; Gregory Allen, the director of AI and advanced technology at the Center for Strategic and International Studies; Julia Stoyanovich, computer science professor and director of the Center for Responsible AI at New York University; and Tim Fist, the director of emerging technology policy at the Institute for Progress.
The House Energy and Commerce Committee will also hold a hearing Wednesday focused on how the federal government can facilitate developments in computing power and AI modeling, including through producing more electricity and next-generation chips. The witnesses are former Google CEO Eric Schmidt, Scale AI CEO Alexandr Wang, Micron Technology executive Manish Bhatia, and David Turk, who was deputy energy secretary under the Biden administration. The hearing follows a request for information from the Department of Energy on building data centers and new energy infrastructure on DOE land. The RFI identifies 16 sites under consideration.

The National Security Commission for Emerging Biotechnology will present its final report at a House hearing on Tuesday and at a public summit two days later. The group was set up by Congress in 2022 and issued an interim report last year warning that the U.S. risks falling behind China absent actions such as increasing funding for biotechnology R&D.
President Trump issued an executive order last week establishing the U.S. Investment Accelerator, which will oversee the CHIPS Program Office and aim to draw investment to the U.S. by helping investors navigate regulations and form research partnerships with the national labs.
The management contract for Jefferson Lab will remain in place for another year after DOE scrapped the recompetition of the contract begun under the Biden administration. DOE stated in February that the Biden-era solicitation did not “align” with the priorities of the Trump administration. The department announced last week that the current contract will be extended through May 2026 and a new competition will commence in the third quarter of 2025.
