House Speaker Paul Ryan criticized Hillary Clinton Wednesday following a State Department watchdog report that the she violated rules during her tenure as secretary of state by setting up a personal email server.

“This report underscores what we already know about Hillary Clinton: she simply cannot be trusted,” Ryan, R-Wis., said in a statement. “Think about this, the highest ranking diplomat in the United States — the secretary of state — deliberately broke agency policy to serve her own interests. Her use of a private email server not only violated department policies, but it was also a clear security risk.”
