The White House said Thursday that the news media are focusing on "petty" stories concerning the Trump administration while ignoring more positive news such as the record-high stock market.

At the day's press briefing, White House press secretary Sarah Sanders said Americans deserve a "more fair, more accurate, and frankly more responsible" news media. But she also said Trump is a champion of the First Amendment.

"The president is an incredible advocate of the First Amendment, but with the First Amendment, with those freedoms, also come responsibilities," she said. "And you have a responsibility to tell the truth, to be accurate."

Sanders went on to tout economic growth and other policy areas she said the administration has made advancements, while accusing the media of ignoring those subjects.

"Frankly, those are the issues that Americans care about, not a lot of the things you cover, not a lot of the petty palace intrigue that you spend your time on," she said. "I think that we need to move towards certainly a more fair, more accurate and, frankly, a more responsible news media for the American people."

Thursday morning, Trump suggested on Twitter that Congress should question news outlets for running "made up" stories.

"Why Isn't the Senate Intel Committee looking into the Fake News Networks in OUR country to see why so much of our news is just made up-FAKE!" he tweeted.

The tweet seemed to be inspired by congressional probes into the proliferation of misleading information on Facebook and by an NBC News report about tension between Secretary of State Rex Tillerson and Trump, which the president has rebutted.
