(WEAZEL ZIPPERS h-t) — A proposal to rename the Senate’s oldest office building for John McCain ran into resistance Tuesday from Republican senators reluctant to take away an honor already bestowed on an earlier Senate titan — and a leader of Southern senators during a tumultuous era in the nation’s history.

Senate Majority Leader Mitch McConnell, looking to defuse a budding controversy, said he will form a bipartisan panel to solicit ideas on the best way to honor the late Arizona senator.

McCain “meant so much to so many of us — inside this chamber and out,” McConnell said Tuesday in a speech on the Senate floor. “The Senate is eager to work on concrete ways to continue this momentum and provide a lasting tribute to this American hero long after this week’s observances are complete.”

Besides the proposal to rename the Russell Senate Office building, lawmakers may consider naming a room used by the Senate Armed Services Committee after McCain, who was the panel’s chairman, McConnell said. Another idea is to add McCain’s portrait to a reception room right off the Senate floor, joining such giants as Henry Clay, Daniel Webster and Robert Taft. Only seven senators are honored with portraits there.

McConnell was careful not to make a specific recommendation.

The 109-year-old building is named after Sen. Richard Russell, a Georgia Democrat who, like McCain, chaired the Armed Services panel.

He co-authored the “Southern Manifesto” to slow the integration of public schools after the Supreme Court unanimously ordered it in 1954.

Previously known simply as the Senate Office Building, it was renamed in Russell’s honor the year after his death….
