【The Devil in Miss Jonas (Der Teufel in Miss Jonas)】

Elon Musk took a subtle swipe at Donald Trump on The Devil in Miss Jonas (Der Teufel in Miss Jonas)Twitter after the president criticized the U.S. justice system.

On Sunday, the CEO of Tesla Motors and SpaceX praised America's judicial arm -- a day after Trump tweeted angrily about a federal judge's decision to block a travel ban on citizens of seven mainly Muslim countries.

Musk, who sits on Trump's economic advisory council, has attempted to position himself as a moderate voice in the president's ear -- someone who can help influence the White House without condoning its most controversial actions.

"Many in America don't realize how proud they should be of the legal system," Musk tweeted on Sunday.

Musk's message followed Trump's sharp criticism of U.S. District Judge James Robart in Seattle, who on Friday temporarily reversed the president's executive order that restricted immigration from Iraq, Syria, Iran, Libya, Somalia, Sudan and Yemen.

The president expressed his outrage on Twitter toward a federal institution that, by design, is supposed to check the powers of the White House and Congress.

Musk is facing growing criticism for his participation in Trump's advisory council.

The tech executive last week defended his decision to remain on the economic council, explaining in a public note that he believes "engaging on critical issues will on balance serve the greater good."

He took another subtle jab at his critics on Sunday, arguing that activists should be pushing for more moderate leaders -- not fewer -- to advise Trump.

At least one tech executive, however, responded to public pressure and dropped out of the presidential forum.

Uber CEO Travis Kalanick last week stepped down from the council after thousands of users deleted their Uber accounts in response to the company's actions during a strike by New York City taxi drivers to protest Trump's so-called Muslim ban.
