Dodd expected to announce his committee decision on Wednesday

Dodd could replace the late Sen. Edward Kennedy (D-Mass.) as chairman of the health and education committee as Congress begins the most critical period of debate over healthcare reform legislation.

Four sources said on Tuesday that they expect Dodd to announce his decision as early as Wednesday morning about whether to leave the chairmanship of the Senate Banking Committee to take up the gavel of the health committee.

Dodd has helmed the committee for most of the year as Kennedy battled brain cancer.

Since Kennedy died, Dodd has remained quiet about the decision.

“We'll make a decision shortly, but not tonight,” Dodd said late on Tuesday.
