115th Congress Leaders

 

The Federal Science Leadership Tracker is an index of high-level federal officials that have responsibility for appropriating funds, setting policy, or managing programs relevant to the physical sciences. The tracker currently contains information about the chairmen and ranking members of selected congressional committees as well as selected Senate-confirmed positions and other leadership positions at key agencies.

This resource is updated on an ongoing basis as new leaders emerge, current appointees depart, and nominees make their way through the Senate confirmation process. Additional committees, agencies, and leadership positions may be added in the future.
