This page has been updated to reflect the selection of Rep. Trey Gowdy (R-S.C.) as chairman of the House Oversight panel.

All eyes are on Robert S. Mueller III as he begins his role as special counsel, leading the Justice Department’s probe into the Trump campaign’s possible ties to Russia. But that’s far from the only investigation into Russian meddling in the 2016 election.

The criminal investigation led by the special counsel is charged with determining if anything illegal occurred. Meanwhile, each of the four major congressional fact-finding investigations is working to expose transgressions it finds unethical.

Despite their differing goals, all the investigations are moving simultaneously and using much of the same information.
