It was understood early in President Wilson's Administration that he believed the exemption was in violation of the treaty, but not until October did he make formal announcement that he intended to ask Congress to repeal it. The question did not come into the foreground, however, until March 5, 1914, when the President addressed this request to Congress in ominous language, which to this day remains unexplained. "No communication I addressed to Congress," he said, "has carried with it more grave and far-reaching implications to the interests of the country." After expressing his belief that the law as it stood violated the treaty and should be repealed as a point of honor, he continued: "I ask this of you in support of the foreign policy of the Administration. I shall not know how to deal with other matters of even greater delicacy and nearer consequence if you do not grant it to me in ungrudging measure."
It has been most plausibly suggested that this obscure language had reference to the Mexican situation, which a few weeks later was to lead to the occupation of Vera Cruz. The European powers were known to be much displeased at the continuing disturbances in Mexico and the American policy of "watchful waiting," and the belief has been expressed that repeal of the exemption was a step to get British support for continued forbearance with Mexico. Other critics have seen a reference to the unsettled issues with Japan and a fear that England might give more aggressive support to her ally if the tolls question were left unsettled. The attempt of a writer of biography to maintain that even in March, 1914, the President and Colonel House foresaw the European war and wanted to arrange our own international relations by way of precaution has been generally received with polite skepticism.
At any rate, the President's intervention in the question, against the advice of his most trusted political counselors, brought down on him a shower of personal abuse from Irish organs and from the group of newspapers which presently were to appear as the chief supporters of Germany. The arguments against the repeal were unusually bitter, and even though Elihu Root took his stand beside the President and against the recent Republican Administration, partisan criticism seized upon the opening. Nevertheless the tolls exemption was repealed in June, and events of July and August gave a certain satisfaction to those who had stood for the sanctity of treaties.
