"Alabama's ties to the Lincoln Assassination: 3 strange tales"

[Thomas Thorne]

Clement Clay surrendered to Federal authorities after he was accused of complicity in the assassination,confidently asserting his innocence.

Clay had been a member of the US Senate in the 1850's and he and wife had been pillars of Washington society. I have read accounts of Mrs Clay going to Washington and lobbying for her husband's release where she was cordially received by even Republican Senators and Representatives. They amazed her by their rejection of the Stanton-Holt general conspiracy involving the Confederate government.

How does this square with the unfootnoted Wiki version which says that both Clays were arrested and imprisoned for a year.? Besides contradicting the account cited above, it would be the only instance to my knowledge of a wife of a prominent Confederate official being incarcerated.
