Michael Davisson has been promoted effective May 1 to senior professional staff member on the Senate Commerce, Science and Transportation Committee's Surface Transportation, Freight, Pipelines and Safety Subcommittee, a move that reflects more than nine years of his congressional service focused on transportation and infrastructure policy.
A Career Built on the Commerce Committee
Davisson's rise through the ranks of the Senate Commerce Committee traces back to early 2019, when he joined as a legislative aide before becoming a professional staff member on the full committee and its surface transportation subcommittee, then called the Surface Transportation, Maritime, Freight and Ports Subcommittee. Davisson's promotion to senior professional staff member on the Senate Commerce Committee panel puts him at the center of surface transportation reauthorization talks, ongoing pipeline safety oversight, and freight security policy heading into the back half of the 119th Congress.
Before joining the Commerce Committee, Davisson spent nearly two years in Sen. Maria Cantwell's personal office, starting as a legislative correspondent in March 2017 before moving up to legislative aide. He holds a BS in mathematics and political science from Santa Clara University.
The Senate staff movement places Davisson in a more senior role on a subcommittee that has been at the center of some of the most contested transportation and energy policy debates of the 119th Congress.
Pipeline Safety at the Forefront
The most advanced legislation tied to Davisson's subcommittee is the PIPELINE Safety Act of 2025, which passed the Senate in late April 2026. The bill reauthorizes federal pipeline safety programs through 2030, raises annual authorization levels from roughly $156-162 million to $185-207 million, and doubles maximum civil penalties to $400,000 per violation. It also mandates cybersecurity rule finalization within 180 days and authorizes $75 million annually in grants to help publicly owned utilities modernize pipeline infrastructure.
Also moving through the committee is the Pipeline Accountability Act of 2025, which has been reported from committee. That bill would require pipelines in high-consequence areas to isolate ruptured segments within 30 minutes, establish new safety standards for carbon dioxide pipelines, and create a new Office of Public Engagement within the Pipeline and Hazardous Materials Safety Administration.
The subcommittee has also taken up the Household Goods Shipping Consumer Protection Act, which was reported from committee in February 2026, and the Rail Service Continuity and Stability Act of 2025, which has similarly cleared the committee.
Senate Staff Role Comes Amid Oversight Battles
A ProPublica investigation raised conflict-of-interest concerns about Trump-appointed officials at the Pipeline and Hazardous Materials Safety Administration (PHMSA), reporting that a senior PHMSA official had previously served as a pipeline industry lobbyist and later signed regulatory notices referencing industry criticism he had personally submitted before joining the government. The investigation reported that PHMSA quietly shelved two major rulemaking initiatives, including one targeting carbon dioxide pipeline safety and another addressing pipeline leaks.
Senate Commerce Committee Democrats responded formally, with Ranking Member Cantwell releasing a statement titled "PHMSA Officials Weakening Federal Safety Protections Amid Conflict-of-Interest Allegations" and demanding documents about the agency's relationship with the Interstate Natural Gas Association of America. Cantwell's office also noted that PHMSA enforcement actions in the first three months of the current administration fell 92 percent compared to the equivalent period in the first Trump administration.
Hearings That Shaped the Subcommittee's Agenda
The Surface Transportation Subcommittee has held a series of hearings in the 119th Congress that frame the legislative work now on Davisson's desk.
In December 2025, the subcommittee held a hearing on modernizing America's rail network, examining the state of freight and passenger rail with an eye toward surface transportation reauthorization. That same month, the panel held a pipeline safety reauthorization hearing focused on the safe and efficient movement of American energy, drawing witnesses from the American Petroleum Institute, the Liquid Energy Pipeline Association, and the Pipeline Safety Trust.
In February 2025, the subcommittee examined cargo theft, focusing on brokering scams, fraudulent trucking companies, and organized train robberies. Homeland Security Investigations has estimated annual losses from cargo theft at $15-35 billion. And in January 2026, the subcommittee held a hearing on the trucking and commercial bus industries, covering Federal Motor Carrier Safety Administration regulations, technology deployment, and workforce challenges.
