I do know that the Logan Act covers what Obama did in Iraq; negotiating with a foreign government.
In a USA run strictly by the constitution, he and Pelosi and many others would be prosecuted for committing felonies.
“The text of the Act is broad and is addressed at any attempt of a US citizen to conduct foreign relations without authority. However, there is no record of any convictions or even prosecutions under the Logan Act”
Kinda toothless...
