Hawaii’s 87-year old junior senator sought medical attention over the weekend and was diagnosed with dehydration, said spokesman Jesse Broder Van Dyke. “He is traveling back to D.C. today and should be casting votes again tomorrow,” Broder Van Dyke said, noting he had just landed in Chicago with the senator and his wife on a flight back from Hono­lulu.

Hawaii-based news outlets first noted that Akaka missed Monday night’s Senate’s ultimately unsuccessful vote to advance the so-called “Buffett Rule.”

In addition to Akaka, Sens. Joseph I. Lieberman (I-Conn.), Orrin Hatch (R-Utah) and Mark Kirk (R-Ill.) missed Monday’s vote. Lieberman was returning from overseas travel; Hatch remains in Utah campaigning for reelection; and Kirk is recovering from a stroke.

But the four missing senators would not have pushed Monday’s results beyond the 60 votes needed to advance the bill.
