During a recent appearance on ABC’s late-night program “Jimmy Kimmel Live,” Mr. Moore gave an account — apparently tongue in cheek — of how he drank a bottle-and-a-half of tequila with Mr. Chávez at the Venice Film Festival in September, and how he mistook Venezuela’s burly foreign minister, Nicolás Maduro, for a bodyguard…

Mr. Moore’s comments “about President Chávez asking him to ‘help’ write his United Nations speech demonstrate Moore’s extreme ego,” Ms. Golinger wrote.

“President Chávez is one of the most brilliant speakers in the world, with an immense capacity to bring together a variety of ideas while being coherent,” she added. “We know that nobody writes his speeches, not even him! He speaks from his heart, and not from a teleprompter!”
