US Attorney David Weiss, appointed by Trump/Bill Barr as Special Prosecutor, was left in place by Joe Biden to finish the job. Normally, a president fires all the US Attorneys, but Biden, determined not to appear tipping the scales in his favor, left Weiss to finish the job, OF HIS OWN SON, and, after 5 years, got two misdemeanor charges. The SC office operates outside the chain of command, and are independent. It is seen as a noble assignment and there is no way in hell Weiss would have took the gig if he had to kowtow to the whims of a President.
To two misdemeanors, crimes for which most people are never prosecuted.
He was charged with a misdemeanor, filing taxes late and underpaying what he owed.
That happened to me, I just paid the tax, in payments, and filed late. No indictment. This is true for most people.
As for the gun charge, few people are ever charged for lying on a gun application form, their permits are just cancelled. Out of 112,000 reported to the US attorney's office in 2017, only 12 were prosecuted.
This is the result of a 5 year investigation. Durham investigated for 4 years and got squat, a 300 page bellyache about the FBi, all old news previously reported on by IG Horowitz.
