As President Donald Trump‘s former campaign chairman Paul Manafort‘s trial looms ahead, special counsel Robert Mueller requested 70 blank subpoenas.

The Hill first reported that this is an additional request for blank subpoenas, as the investigation team had previously asked for 35. Manafort was charged with bank fraud and money laundering, and he surrendered himself to the Federal Bureau of Investigation.

Manafort allegedly moved millions of dollars to offshore accounts and used the money for luxury goods. The indictment alleges that he laundered over $18 million in offshore accounts.

He faces 18 criminal charges in Virginia federal court and five more in D.C., all of which he has pleaded not guilty for. Rick Gates was also charged with fraud. During his investigation, Mueller found that both Manafort and Gates lobbied with Ukrainian firms.

Manafort launched a countersuit against Mueller’s investigation in January, saying that Mueller is inquiring about events that took place before Trump campaigned for presidency.
