Looks like Manafort may have been engaging in some witness tampering:

Special counsel Robert Mueller’s office on Monday accused Paul Manafort, the former Trump campaign chairman, of tampering with witnesses ahead of his upcoming trial on charges involving illegal lobbying work.

In an 18-page motion filed in the U.S. District Court for the District of Columbia, prosecutor Andrew Weissmann called for an immediate hearing to determine whether Manafort violated his bail terms when he and another, unidentified person repeatedly contacted two other unnamed people “in an effort to secure materially false testimony” concerning the activities at the center of February’s superseding indictment.
Trump hires all the best people!
