The ascension of President Vladimir Putin following Yeltsin's resignation on December 31, 1999 brought many new changes to the Federation Council. As part of his top political goals in his first months of office in 2000, Putin proposed a reform law to change the makeup of the Council which would allow regional governors to designate councillors but not sit on the Council themselves, freeing it from what Putin saw as blatant personal cronyism on the part of regional leaders. The Council furiously resisted Putin's plan, conscious that their role in federal politics, their very ability to enjoy the fruits of living within Moscow, and their parliamentary immunity would end. With the State Duma threatening to override a Council veto, and Putin's threats to open federal criminal investigations on regional governors, the Council backed down and grudgingly supported the law in July 2000. In their place, a wave of new Kremlin-friendly senators took the vacated seats, complete with the full backing of Putin. The last of these dual senator-governors were rotated out of office in early 2002.
