In a 12-1 vote, the D.C. council on Tuesday voted in support of Chairman Kwame Brown’s rearrangement of committee posts, including the shocking removal of Council member Tommy Wells (D-Ward 6) from the transportation committee.

Wells, the only one who dissented, took his disapproval to Twitter Wednesday morning and said: “Impressed I had no support from my colleagues today but Chair can make council member lives miserable.”

News outlets and Twitter users speculated the committee switch was retaliation for Wells’ investigation into Brown’s use of costly luxury SUVs that were leased by the city. On Tuesday, Brown quickly refuted that idea and tweeted: “…the committee changes will take place, but it has nothing to do with any SUV matter.”

The economic development committee, which was open after Council member Harry Thomas Jr. resigned due to a $1 million lawsuit by the Office of Attorney General, will be overseen by Brown.

Wells will oversee the planning, parks and recreation committee. “I am going to object on this highly unusual action by the chair,” Wells said at the hearing on Tuesday.

Council member Mary Cheh (D-Ward 3) will take over Wells’ transportation post.
