WaPo: “In an evenly divided Senate, subpoenas are issued on a bipartisan basis. But having 51 Democratic senators in the next Congress would give Democrats on key committees unilateral control over investigations.
If Democrats used that power wisely but aggressively,they could demonstrate to the country what congressional oversight looks like when it’s genuinely conducted in the public interest. That alone would reflect terribly on McCarthy’s House, which is likely to devolve into a 24/7 spectacle akin to Fox News meets “The Krusty the Clown Show.”
Democratic-controlled Senate committees would presumably focus in part on Trump’s efforts to profit off the presidency, because that has again become a major public issue.”
