File No. 812.00/427.
The Acting Secretary of State to the American Ambassador.
In reply to your telegram of the 18th, it seems impossible for this Government to act except for violations of the neutrality or penal laws of the United States, but in case of such violation prompt action will follow, now as heretofore, directions to that end having already been sent by the Department of Justice to its agents in Texas, who will watch developments carefully and prosecute vigorously any violators of the law. Such agents report inability thus far, to secure evidence of violation of the neutrality statutes. The ambassador is instructed to urge the Mexican Government to report all information they may have to this Government, who will fully cooperate with them.
