Brzezinski said on-air Thursday that after reaching out to Durbin's office, a spokesperson reiterated that the senator stands by his claim and that a colleague will "verify" his account.
"His spokesman says the senator is standing by the claim and said that another senator today will verify Durbin's story," Brzezinski said.
Durbin wrote on his Facebook page on Sunday that during a recent closed-door meeting, a House Republican told Obama, "I cannot even stand to look at you."
White House spokesman Jay Carney said Wednesday that after talking to a participant in the meeting, the alleged exchange "did not happen." House leadership also repudiated Durbin's claim and demanded an apology.
