Sen. Johnson Suffers Possible Stroke

(AP) Democratic Sen. Tim Johnson of South Dakota suffered a possible stroke Wednesday and was taken to a Washington hospital, his office said.

Johnson became disoriented during a call with reporters at midday, stuttering in response to a question. He appeared to recover, asking if there were any additional questions before ending the call.

If he should be unable to continue to serve, it could halt the scheduled Democratic takeover of the Senate. Democrats won a 51-49 majority in the November election. South Dakota's governor, who would appoint any temporary replacement, is a Republican.
