Sick of seeing this.
Sorry, no.
Co-equal branches of government remember?
The Speaker of the House has the right to invite anyone he please to address the House and the Majority Leader has the right to invite anyone he pleases to address the Senate.
The president is not the ruler of the country. The White House was notified before the invitation was accepted. They didn't like it, but that is fine. There is nothing that says they must. It was a curtsy notification.
Excellent post
