(Above) Sen. Tom Cotton (R-Ark) practices Sousaphone during Iranian Negotiations with Congress

In what the Obama administration called an unprecedented violation of proper diplomatic procedure, Senator Tom Cotton (R-Ark) began playing sousaphone feet away from the Oval Office entrance.

Senate Republicans clarified that the young senator is merely practicing his instrumentality and developing a healthy appreciation for the arts, but the executive branch believes that the senator’s four-hour long renditions of “Who’s Who in Navy Blue” may mask a more nefarious purpose.

“The Oval Office is no stranger to the beautiful sounds of sousaphones, but what Senator Cotton has done is flat-out irresponsible,” White House Press Secretary Josh Earnest said on  Monday. “There is a time and place to play a 1920 military march, but pressed against the door of the Oval Office while President Obama negotiates nuclear deals is not one of them.”

According to the White House, Senator Cotton’s swinging of his sousaphone’s metal frame against the office door and continuing the march with only mouth-sounds has forced Obama to prematurely end several talks with Iranian President Hassan Rouhani.

“I love John Philip Sousa, no one can ever claim to the contrary,” Obama said in a release Wednesday. “Heck, sometimes when Michelle and the girls are away I delight Bo with my unconventional take on ‘Nobles of the Mystic Shrine.’ But as soon as your BB♭’s annoy the Ayatollah Khomeini, they annoy me.”

Senate Majority Leader Mitch McConnell defended Cotton’s brass as a tried and true negotiation tactic and reminded the public of Senator Hubert Humphrey’s famous trombone rendition of Miles Davis’s “Kind of Blue” that drove the US into Vietnam.
