Senator Elizabeth Warren doesn’t seem too unhappy about being labeled “dangerous” by investor Peter Thiel .

Thiel, who co-founded PayPal, Palantir and Founders Fund, made the comments in an interview on Fox News with Tucker Carlson, where he described most of the Democratic presidential field as “equally unimpressive” and called Warren “the dangerous one.”

“I’m most scared by Elizabeth Warren,” he said. “I think she’s the one who’s actually talking about the economy, which is the only thing — the thing that I think matters by far the most.”

Warren tweeted a link to a Bloomberg story about Thiel’s remarks with a succinct response of her own: “Good.”

Thiel is a high-profile backer of libertarian causes and a Trump supporter — a fact that’s made him a controversial figure in Silicon Valley — so it’s hard to imagine that many Democratic primary voters will be following his recommendations. Indeed, to some, Thiel’s criticism could be seen as an endorsement.

During the same interview, Thiel — who sits on Facebook’s board — repeated points made in an earlier speech where he accused Google of “seemingly treasonous” conduct and said the government should investigate the search giant’s ties with China. (China being the main target in Trump’s trade war.)

Warren, who’s been gaining in some recent polls, has some thoughts on tech policy as well, having called for the breakup of Google, Amazon and Facebook and also proposed an equity fund for underrepresented entrepreneurs.
