If the Obama WH visitor logs are correct, C. Handler was with Obama on his Brazil, Chile and El Salvador trip (3/19/2011 to 3/23/2011) meeting with the President of each Country. If not, CH than some of her "models" made the trip……or was CH arranging meetings thru her vast "model" and "art" network to keep the foreign Presidents entertained?
