Special counsel Robert Mueller could issue new indictments as soon as Tuesday in the ongoing probe of the Trump campaign's ties to Russia.

CBS News reports that indictments could be handed up in the sprawling case, which has already resulted in guilty pleas by top officials who worked to elect President Donald Trump.

Sources with knowledge of the investigation told the network's Paul Reid that they expect the indictments this week, possibly right away.

“I’ve spoken with many sources with knowledge of the Special Counsel investigation, and we do expect new indictments to be coming as soon as today," Reid said.

The president's former personal attorney, Michael Cohen, was in Washington, D.C., on Monday to meet with Mueller's investigators.

Donald Trump Jr.'s friends have said they believe the president's son will be indicted in the case, and prominent "birther" Jerome Corsi and longtime Republican "dirty trickster" Roger Stone have each said they expected to be indicted.
