From a 2/13/1893 article of "The Internal Revenue Record and Custom Journal" giving American inventors another chance. Some of the debate as described:

Fifty-Second Congress—Second Session
The provision in the Army Appropriation bill inserted by the Senate, in regard to the extension of time for the submission of American inventions of small arms, has been finally adopted. The conferees after considerable debate on the subject agreed to the Senate amendments with modifications fixing the limit within which invention must be submitted at July 1, and providing for the trial of inventions submitted either by the Ordnance and Fortification Board, or a board especially appointed for the purpose by the Secretary of War. As passed by the Senate the former was required to make the test. In considering the proposed extension of time the House Military Committee had before them the recent invention of Capt. White, of the Marine Corps, and it is understood were greatly impressed with its merits.
The House conferees opposed the amendment. They concur to the opinion of the Chief of Ordnance, that there should be no further delay in the equipment of our troops with a modern magazine gun, and that the manufacturer of the Krag-Jorgensen should be proceeded with until an American invention of superior merit is developed. They prefer the method proposed by the circular of Gen. Flagler, issued early in January, in which instructions are given American inventors as to the lines on which they should work for improvements on the Krag-Jorgensen gun. The Senate conferees were equally persistent in their demands for three months in beginning the manufacture of a new weapon. Nearly all the other important items of differences between the two houses have been agreed to. (This last sentence was dealing with issues other than magazine rifle adoption.)

Article in the "Army and Navy Journal" dated 8/11/1900. Not sure who wrote this letter, but the Journal suspects "the leader of the Filipino forces". But the writer had an axe to grind and defended the Krag rifle in a cynical/scathing manner. Not sure who "Aggie" is. He is referring to the above comments by the three senators.

THE KRAG AN UGLY GUN
    We have received the accompanying communication, which appears to come from the leader of the Filipino forces, though why he should address us so familiarly we do not know. It has certainly not been our intention to endear ourselves to Aguinaldo.
    Biae-na-Bato, or Some Other Place, Any Old Day.
Dear Army and Navy Journal
    I have just read with interest in your issue of May 12 the views of Senators Teller, Hawley and Warren concerning the Krag-Jorgensen gun. I agree with them that it will be well to change the gun of the Americanos. I do not like the Krag at all. They are right in saying it is an "ugly" gun. It is a second rate gun, for in all the tests which I have held in the Philippines it has been after my Remingtons. Another objection is that it does not get out of order, and honest Filipino workmen in the repair shops in Manila are deprived of their occupation.
    The United States should at once appoint a board consisting of these three Senators who are experts on guns, and I would suggest that they adopt the Ladies' Model Stevens .22 caliber, short, which is a beautiful gun. Yours,        AGGIE
    P.S.-After you adopt the new gun, would not my friend Carl Schurz arrange it so that I can buy the retired Krags cheap?      A.
    P.P.S.-The 32 field pieces and the Hotchkiss guns have also been severely criticised by my soldiers, and the Gatlings are not so good as they should be.         A.

Man am I slow. Now I get it after your reply. So I imagine somebody wrote as an imposter "Aggie". To what end I am not sure.

Wow, I was posting some cartoons and see that you beat me to it!
