A report that Ivanka Trump sent hundreds of emails to administration staffers and officials using her personal email in violation of federal rules is prompting a call for an investigation and at least one former White House staffer is calling it “hypocritical.”

Sen. Richard Blumenthal, a Connecticut Democrat, told CNN that “there should be some kind of investigative effort, whether it’s through the Office of Government Ethics or through the Congress.” Blumenthal said there’s a need to hold the Trump administration accountable, even as Democrats and Republicans try to work on issues in the next Congress including infrastructure and immigration.
