The Clinton campaign has raised an estimated $11 million in online contributions in the last 72 hours, and has committed to six-figure ad buys in crucial swing states, according to campaign sources.

“The Trump campaign claims their path to the White House is through states like these, but we’re going to make sure those doors remain shut. Fueled by record-breaking fundraising in the last 72 two hours, we are supercharging our GOTV program with these ads to make sure voters know the urgency and the stakes of voting on Nov. 8,” Clinton’s Deputy National Press Secretary Jesse Ferguson said in a statement made available to the Washington Examiner.
