President Trump has sought repeatedly to punish journalists for the way they ask him questions, directing White House staff to ban those reporters from covering official events or to revoke their press credentials. He has also asked that retaliatory action be taken against them. Until this week ... Trump's senior aides have resisted carrying out his directives. On Wednesday, however, newly installed Deputy Chief of Staff Bill Shine and press secretary Sarah Huckabee Sanders took action against CNN correspondent Kaitlan Collins, telling her she could not attend Trump's open-media event in the Rose Garden because they objected to her questioning of the president earlier in the day. The move revealed a fresh willingness inside the West Wing to execute the president's wishes to punish reporters. It immediately drew a chorus of protest throughout the media, including from Fox News Channel, Trump's favorite network and Shine's former employer. Olivier Knox, president of the White House Correspondents' Association, said the group would challenge any further efforts by Trump to curtail the access of reporters who offend him. In keeping with the spirit of the First Amendment, reporters who cover the White House should be free to do their jobs without the specter of reprisal from the government," he said in a statement. During his campaign, Trump barred reporters from about a dozen media organizations ... from being credentialed at his rallies, news conferences and other events.
