John Kennedy actually said...

"I take particular pleasure in welcoming you to this country."

"I hope that your visit here to the United States will remind the people of this country that they have a good deal of unfinished business in this hemisphere."

"We stand with Venezuela, we stand with you, in the fight for freedom during these great days of the sixties."

"It is a great pleasure to welcome you and Madame Betancourt to Washington and especially here at the White House."
