Motions indicate probe into former D.C. mayor will continue

The long-running federal investigation into former District of Columbia mayor Vincent Gray’s 2010 campaign will continue at least through December.

Prosecutors filed motions Tuesday to postpone court appearances for two of the six people who pleaded guilty to felonies related to their efforts to help Mr. Gray get elected.

Businessman Jeffrey Thompson has admitted setting up an illegal $660,000 slush fund that aided Mr. Gray’s campaign. Prosecutors have said Mr. Gray knew about the money. The motions filed Tuesday say Thompson and campaign aide Vernon Hawkins are still cooperating with the investigation and seek to postpone their next court appearances until December.

Mr. Gray lost his bid for re-election in the 2014 Democratic primary. He has been under investigation for more than 4 ½ years without being charged with or accused of a crime.
