The Latest: Roger Stone arrives at court for his arraignment

WASHINGTON (AP) — The Latest on Donald Trump confidant Roger Stone (all times local):

10:25 a.m.

Donald Trump confidant Roger Stone has arrived at the federal courthouse in Washington as he faces charges in the Russia investigation.

Stone arrived Tuesday in a black SUV wearing an all-blue suit and tie. He waved to a small crowd of supporters and protesters, including some yelling, “Lock him up.”

The longtime political operative is appearing for his arraignment after spending the weekend blasting special counsel Robert Mueller’s case against him as politically motivated.

Stone was arrested in Florida last week and is charged in a seven-count indictment with obstruction, lying to Congress and witness tampering.

Prosecutors say Stone lied about the contents of his discussions with the Trump campaign involving WikiLeaks and hacked material damaging to Hillary Clinton that the anti-secrecy group released during the 2016 campaign.

After a weekend of publicity and television news appearances, Roger Stone will come before a federal judge who may look to silence the Donald Trump confidant.

Stone faces a Tuesday morning arraignment in Washington, where he is expected to plead not guilty to charges that he lied to Congress and engaged in witness tampering.

Stone is a self-described dirty trickster and longtime confidant of the president. He has asserted his innocence in a series of TV interviews since his pre-dawn arrest Friday in special counsel Robert Mueller’s Russia investigation. Being outspoken is an unusual strategy given that most defendants tend to stay quiet as their case proceeds.

It’s unclear whether Mueller’s prosecutors will look to have Stone locked up, and whether Magistrate Deborah Robinson might impose a gag order.
