Russert: Clinton cancels morning show appearances (UPDATED)

Tim Russert, a colleague reports, just said that Hillary Clinton canceled her scheduled appearances on the morning shows tomorrow.

It's a sign of weakness she can ill afford at a moment when questions about whether she can continue are mounting.

UPDATE:Clinton spokesman Phil Singer denies Russert's claim: "She was never booked on am shows. This item is wrong. Russert got it wrong."
