Hillary Clinton vowed to stay involved in politics and fight to make sure President Donald Trump does not continue to undermine the country's values, the 2016 Democratic presidential nominee told The Washington Post's Jonathan Capehart in an interview published on Tuesday.

Speaking to Capehart in the latest episode of "Cape Up," Clinton called Trump a "con artist" and an "equal opportunity bigot."

She used the current debate over tax reform to demonstrate her belief that Trump is a fraud, saying that for all the president's talk that the GOP tax plan is about helping the middle class, it's really "meant to put money into the pockets of him and his family.

"It's meant to save his estate and therefore his children from having to pay taxes on whatever it is he's worth. It's meant as a gift to billionaires who he pays more attention to than the folks who put their faith in him during this election."

Clinton also lashed out at Trump for "willing to use the dog whistle to attract people who had racial animosity, bigotry, prejudice" during the campaign as sort of "an equal opportunity bigot."

Clinton said that Trump "went after immigrants and foreigners and he was very sexist and homophobic, and he was obviously Islamophobic. But he kept coming back to race and he was really stirring up a lot of feelings and rhetoric."

Although Clinton said she hoped he would not continue this tactic once he became president, "I think that Trump still plays that race card all the time. I really regret that, because I think he does it for opportunistic political purposes. When in trouble in the Congress or the Russian investigation, his go-to targets are President [Barack] Obama and me, and African-Americans."

Clinton charged that the president is "a little obsessed with me, but I think it's partly his own ego because he knows I got more votes and he knows that there are questions about the election that deserve answers.

"And he knows I'm still speaking out, I haven't retreated under a rock somewhere. But, it's also part of his political strategy. It is something that he knows his hard-core supporters will respond to, and he's trying to keep them on board."

The former secretary of state, senator from New York and first lady also discussed coming to terms with the fact that millions of people simply don't like her, saying that is something hurtful and difficult to digest.

Clinton said she very much wanted to be president, but perhaps one of the reason she did not achieve her goal was that she is by nature a reserved person.

"I knew that I was ready to do the job, I felt I was qualified, that my experience really gave me the tools that were needed for our country at this point in our history, but I confess I'm not as sure that I conveyed that as strongly as I wish I had," she said.

Clinton expressed the difficulty in continuing after such a setback, but said she has received so much energy and inspiration from her book tour.

"There's a lot of crying at my book signings, a lot of really tearful encounters, because people are still so emotional about how they feel. People tell me their stories, even in the short moments that I have with them, about what they're now doing to try to be resilient themselves.

"I just can't tell you what it's meant to me… And I know that we've been knocked down, but we're getting back up. And we're not going to let this Congress take away the rights of people. We're not going to let this president continue to undermine our values. We're just not gonna let it happen. And that's why I'm going to stay involved in politics."
