In the spring of 1876, the presidential campaign was on the horizon and Blaine was a prominent candidate for the Republican nomination. Meanwhile ugly rumors were flying about concerning the connection of certain members of Congress, Blaine among them, with questionable railroad transactions, and he arose in the House to deny the charges. He did not discuss the matter fully, as he did not wish his Maine constituents to know that he had received a large commission for selling Little Rock securities. Gossip grew, however, and a congressional investigation resulted in May, 1876. Blaine was one of the witnesses, but was doubtless anxious to bring the investigation to an end, since it clearly reduced his chances of receiving the nomination. Presently gossip said that Warren Fisher and James Mulligan were going to testify. Mulligan had been confidential clerk to one of Mrs. Blaine's brothers and later to Fisher. When Mulligan began his testimony it appeared that he intended to lay before the committee a package of letters that had passed between Blaine and Fisher, and thereupon, at Blaine's whispered request, one of the members of the committee procured an adjournment for the day. That evening Blaine found Mulligan at the latter's hotel and prevailed on him to surrender the letters temporarily, in order that Blaine might read and then return them. Blaine thereupon consulted two lawyers and on their advice he refused to restore the package to Mulligan. Merely to keep silence, however, was to admit guilt. Blaine, therefore, arose one day in the House of Representatives and holding the letters in his hand read selections and defended himself in a remarkable burst of emotional oratory. At the climax of this defence he elicited from the chairman of the committee of investigation an unwilling admission that the committee had suppressed a dispatch which Blaine declared would exonerate him. Blaine was triumphant, his friends sure that he had cleared himself and the matter dropped for the time. Further investigation was prevented by Blaine's refusal to produce the letters even before the committee and by his sudden illness shortly afterward. His election to the Senate soon took him out of the jurisdiction of the House committee and no action resulted.
