Just passing this along, but the source — Josh Marshall at Talking Points Memo — isn't known to go off half-cocked. Marshall posts tonight that Rep. Henry Waxman was taken to Cedars-Sinai here in L.A. this afternoon. Waxman's office, according to Marshall, "confirmed to us that the Congressman wasn't feeling well today, and went to a hospital for what were described as routine checks. Further details were not immediately available, and the source was unable to confirm which hospital Waxman was taken to."
