CNN has filed a lawsuit against President Donald Trump. The American news channel wants his reporter Jim Acosta to be admitted to the White House again. Last week, Acosta’s accreditation was withdrawn after an incident at a press conference by President Trump.

CNN finds the decision of the White House unfounded and relies on the American constitution. In addition to Trump, chief of staff John Kelly, press secretary Sarah Huckabee Sanders and three other government officials have been summoned by the news channel for their role in the suspension of Acosta.

The CNN reporter collided with Trump at a press conference on the outcome of the mid-term elections when he asked questions about Trump’s remarks about immigrants during the election campaign. A White House employee tried to grab the microphone from the journalist. That prevented Acosta from pushing her hand away.
