Obama does need to resign or be removed from office. If the Democrat Party won't do what's best for America and Congress won't do their job of oversight of the Executive branch of government, then it's the military who took an oath to uphold and defend the Constitution and Obama isn't above the Constitution but Obama may disagree.
The only thing left is the Constitution and the original intent of the Second Amendment.
‘This is not peace, it is an armistice for 20 years.’ (Ferdinand Foch. After the Treaty of Versailles, 1919).
