According to one newspaper, Martha Todd, when returning south from Washington in 1864, brought with her "[???], worth at least $30,000".
The New York World commented on that: "...the contents of his wife's sister's trunks are giving aid and comfort to the enemy - not least is the shock which these facts will give to the loyal hearts whose hopes and prayers and labors sustain the cause which is thus betrayed in the very White House." Bad publicity, even if untrue, in an election year.
