Clear it with Sidney

“Clear it with Sidney” was Franklin D. Roosevelt’s instruction to Bob Hannegan during the 1944 Democratic convention: before a vice-presidential choice was settled, Hannegan was to consult Sidney Hillman, whose approval Roosevelt treated as decisive. The phrase compressed a private negotiation over political power into a public slogan, and Republicans later used it to challenge Harry S. Truman’s independence.

Meaning and Reference

“Sidney” was Sidney Hillman, the labor leader who directed the CIO Political Action Committee. Roosevelt’s words meant that Hillman was to have the final say in the decision under discussion. They were not merely a reminder to pass along information: in the account of the conversation, they made Hillman’s approval a necessary step in the process.

The Private Conversation

On July 15, 1944, four days before the convention was scheduled to open, Truman drove from Kansas City to Chicago. That afternoon Roosevelt’s westbound train made an unscheduled stop there. The President was traveling toward San Diego and a meeting with Douglas MacArthur, but his train was moved onto a siding so Hannegan could join him for a private conversation of about half an hour in the Ferdinand Magellan presidential railcar.

The meeting was kept out of public view. Roosevelt’s secretary, Grace Tully, later wrote that the train remained in the Chicago yards and that none of the party showed themselves outside. Most of the conversation stayed secret, but the instruction to “Clear it with Sidney” endured as its most recognizable line. Hannegan left the train carrying a letter on White House stationery, but the phrase and the letter were distinct elements of the episode: the instruction expressed Roosevelt’s demand for Hillman’s assent, while the letter named Truman.

Hillman’s Influence

Hillman’s position helps explain why the instruction mattered. He led the well-funded CIO Political Action Committee, a new force in American politics, and Roosevelt’s wording gave him authority in a decision being handled by party leaders. Yet Hillman was not simply one of their circle. He was not even a registered Democrat, and his earlier work in the Office of Production Management had brought him under heavy criticism from the Truman Committee, which had been largely responsible for his removal.

That history made the directive politically suggestive. Hannegan and other party chiefs regarded Hillman as an amateur and did not wholly trust him, despite his political resources and allegiance to Roosevelt. The phrase exposed a tension between the party officials managing the convention and an outside power broker whose approval the President nonetheless required. When Hannegan later repeated the instruction at a private dinner in Chicago, he seemed to regard the requirement as a formality; its effect was to make explicit that Hillman’s voice could not simply be bypassed.

From Instruction to Campaign Taunt

During Truman’s campaign, Republicans turned the phrase into a war cry, using “Clear it with Sidney” to make the convention’s private arrangement an issue against him. The line invited voters to see Truman as dependent on Hillman and the labor organization behind him. It was a compact political charge: a few words about consultation could be recast as evidence of who really held influence.

The attack formed part of a wider effort to make Truman a liability, but attempts to uncover damaging material from his Pendergast years came to nothing. The phrase nevertheless gave opponents a ready-made symbol. Its afterlife depended on the gap between its original setting—a concealed conversation about convention business—and its later public use as an accusation about Truman’s political loyalties.
