>> FBI and DoJ have been refusing to allow their personnel to testify to Congressional committees - that is, personnel below the top few officials.
This will be the next bomb that drops. The FBI and DOJ are EXECUTIVE branch offices, and, by the Constitution, MUST follow the orders of the Chief Executive - Congressional laws and previous presidents signing laws be damned.
Trump has the POWER and the AUTHORITY to order the lower level people be allowed to testify.
It is time for him to EXERCISE the authority of his office.
