The Justice Department will appeal a federal judge's ruling that President Trump can't legally block people from his @realDonaldTrump Twitter account based on their political views, according to court documents filed late Monday.

Last month, Judge Naomi Buchwald said in a 75-page decision that Trump's effort to silence his critics on Twitter is not permissible under the Constitution because the digital space where he engages with constituents is a public forum.
