$\textit{CP}$ violation in $B_s^0 \rightarrow J/\psi \phi$ at the Tevatron

The author reviews the history and present status of CP violation measurements made during RunII of the Fermilab Tevatron. Both flavor-tagged and untagged measurements of the Cp-violating phase {beta}{sub s}{sup J/{Psi}} are discussed, as well as measurements of the width difference {Delta}{Lambda}{sub s} between heavy and light B{sub s}{sup 0} mass eigenstates made in the B{sub s}{sup 0} {yields} J/{Psi}{phi} system.
