It took me a moment or two to digest the quote I read about what Donald Trump reportedly said to Lindsey Graham, the South Carolina Republican U.S. senator who transformed himself from a severe Trump critic to one of the president’s most ardent sycophants.

Graham is angry over the president’s decision to pull troops out of Syria and his abandoning of our Kurdish allies who have fought with us in the war against the Islamic State.

The Associated Press said that Trump told Graham, “I am the boss.”

The boss? Of what? Of whom?

Trump is the “boss” of the executive branch of the federal government. He has no authority over the legislative branch, of which Graham is one of 535 House and Senate members. The Constitution grants Congress “co-equal” power with the executive branch.

Graham, despite his disappointing fealty to Trump, does recognize that South Carolina’s voters sent him to the Senate to do their bidding and to stand up for himself when the need arises. He doesn’t work for Trump. He doesn’t have to do a single thing the president might demand of him.

As an MSNBC blogger, Steve Benen, reported: “With all due respect for the president, I think I’m elected to have a say about our national security,” Graham said. “I will not be quiet. I will do everything I can to help the president get to a good spot, but if we do not leave some residual forces behind to partner with the Kurds, ISIS will come back, it will put our nation at risk, we will have been seen as dishonorable in the eyes of all future allies.”

So, there you have it. Sen. Graham is beginning to show a bit of the spine he exhibited while campaigning against Donald Trump for the 2016 GOP presidential nomination. I hope it continues to stiffen … although I am inclined to doubt that it will.
