Hillary Clinton returned to Washington Monday for the first stop promoting her new book “What Happened.” Hours earlier, Clinton said she has not ruled out contesting the 2016 election.

"I think that this President and those on an alternate reality track are posing a clear and present danger to the future of our country,” said Clinton to a sold out at the Warner Theater. Some in the crowd paid hundreds of dollars for a ticket.

Clinton said some of her book, already a bestseller, is about internet rumors taken as truth. She pointed to The Pizzagate conspiracy and the Comet Ping Pong gunman. Moderator Lissa Muscatine, owner of neighboring Politics and Prose bookstore, said after the shooting the Clintons wanted to help, so they ordered pizzas from Comet and sent them to a local literacy program.

“This is a terrible example of what can be done by people who are malicious,” said Clinton.

The discussion included some questions read from the audience. One sought Clinton's advice to federal employees in our area, adding the Trump administration is destroying agencies.

“If you can stick it out, stick it out,” said Clinton. “Because the tide has to turn”

Clinton, concerned about the outcome of upcoming midterm elections, twice mentioned the need to mobilize voters in Virginia. Last November, she won the state by only five points.
