2/ A Constitutional appellate lawyer, Schaerr, representing an unnamed member of Trump’s campaign and transition, is suing the government for records, looking for evidence that the intel agencies illegally “unmasked” (under the FISA warrant) members of the Trump team
3/ Manafort is trying something similar (filing complaints that the Mueller probe itself is illegal). Claiming that the prosecutor is behaving illegally and the evidence was illegally gotten are Hail Mary defenses.
