Lying to a congressional committee while you are under sworn oath is illegal.  Attorney General Jeff Sessions should resign and at the very least must recuse himself from the investigation into illegal collusion between Vladimir Putin, the Russian government and the Trump Campaign.  President Trump’s failure to release his tax returns (unlike any other presidential candidate or President) continues to be a cloud over his Administration.  An open and transparent review of his tax returns could answer questions related to whether or not he or his company have ties to Russia.
