• Paul Manafort is being investigated for possible money laundering by the US attorney's office for the Southern District of New York.
• The list of probes against Manafort continues to grow amid special counsel Robert Mueller's own investigation into possible money laundering.

President Donald Trump's former campaign manager Paul Manafort is being investigated for possible money laundering by another federal agency, according to three sources in a Wall Street Journal report on Tuesday.

The US attorney's office in New York's Southern District was reportedly working in conjunction with special counsel Robert Mueller's probe into potential money laundering from Manafort - part of a wider examination into Russia's meddling in the 2016 US presidential election, The Journal reported.

The news of the probe comes amid a Politico report last week that said Trump was interviewing US Attorney candidates to head the attorney offices for New York's Southern District, based in Manhattan, and Eastern District, based in Brooklyn. Trump was considering nominees that reportedly had ties to his associates, including his personal lawyer, The Journal reported.

"I never heard of a president interviewing a US attorney candidate," Richard Painter, a University of Minnesota law professor who served as Bush's chief ethics lawyer, previously told Business Insider.

Manafort has previously denied the money-laundering allegations.

The list of probes into Manafort's affairs continues to grow, as prosecutors who specialize in money-laundering cases have recently been recruited to Mueller's team, and investigators continue to ramp up their investigation into Russia's involvement in the election.
