WASHINGTON (AP) — The special counsel in the Russia investigation is still considering filing new charges against former Trump campaign chairman Paul Manafort after his plea deal fell apart over allegations of lying to investigators, prosecutors said Friday. The development in Manafort’s case comes at a time of frenetic activity in special counsel Robert Mueller’s investigation as prosecutors obtained a guilty plea from President Donald Trump’s longtime fixer and appear to be lining up charges against another Trump supporter. Prosecutors this week revealed that Manafort’s plea deal had fallen apart after they say he repeatedly lied to investigators.
