Sheheke traveled with Lewis and Clark to meet United States President Thomas Jefferson. On October 20, 1804, two Mandan leaders, each considering himself the principal chief of Matutonka, came to visit the captains.

" The captains meant well, but they only worsened an enmity between the Mandan leaders.
