MS NOW, CNN and Politico have filed a federal lawsuit against President Donald Trump and senior administration officials, challenging the decision to bar their journalists from the White House.

The three news organizations are asking a federal judge in Washington, D.C., to restore their reporters’ press credentials and access to the White House while the case proceeds. The lawsuit argues that the administration violated constitutional protections by restricting access in response to coverage it considered unfavorable.

The legal challenge follows Trump’s announcement on Friday that the three outlets would be banned from the White House. The restrictions were enforced Saturday, when journalists from the organizations were denied entry and their press credentials were confiscated or disabled.

The organizations argue that the decision amounts to viewpoint-based discrimination and violates the First Amendment. They also contend that the administration failed to provide adequate notice or an opportunity for the affected organizations to respond before revoking their journalists’ access.

In a joint statement announcing the lawsuit, the outlets said they were seeking to protect their constitutional rights and the principle that government officials should not determine what the press can report or publish. They argued that allowing the restrictions to remain could affect independent journalism and the public’s access to information about the federal government.

Trump has defended the ban by accusing the outlets of publishing what he describes as false or unfair coverage. He has also indicated that other news organizations could face similar restrictions.

The White House had not immediately commented on the lawsuit, according to reports. The case is expected to bring the administration’s dispute with major news organizations into federal court, where judges will consider the constitutional and procedural issues surrounding the press restrictions.
