Former President Donald Trump's indictment by a New York grand jury has thrust the nation into uncharted political, legal and historical waters, and raised a slew of questions about how the criminal case will unfold.

Despite his online bravado, former President Trump was surprised and “subdued” by the Manhattan grand jury’s indictment, says Guardian reporter Hugo Lowell. He joined MSNBC legal analyst Lisa Rubin to discuss the New York case and why Trump is “extremely likely” to receive a gag order from the judge.

Acting New York Supreme Court justice Juan Merchan will preside over the criminal prosecution of former President Trump after signing off on a plea deal with Trump Org. executive Allen Weisselberg last year.

Donald Trump has become the first former president to be indicted in a criminal case after a grand jury investigation into hush money payments made on his behalf during the 2016 presidential campaign.

Donald Trump was indicted by the Manhattan District Attorney's office following an investigation related to hush money payments to a porn star who has said she had a sexual relationship with him, a law enforcement source said,

Some of the reasons appear to concern how federal prosecutors viewed Donald J. Trump’s longtime fixer, Michael D. Cohen.

The indictment marks the first time in American history that a U.S. president has been prosecuted on criminal charges.
