I've heard in a few places that Rep. Raul Grijalva indicated buses with immigrant children were scheduled to arrive in Oracle Tuesday but that they wouldn't arrive. I called Grijalva's office. Someone in the office confirmed that Grijalva received a one line message from Health and Human Services saying no buses would arrive in Oracle Tuesday, but it did not say the buses were previously scheduled.
Here are the first two paragraphs in the story on the KPHO News site:
A U.S. Representative from southern Arizona said he's been informed that buses bringing about 60 illegal immigrant children will not arrive in Oracle as previously scheduled Tuesday.
Rep. Raul Grijalva, a Democrat from Tucson, said his office received a one-line email from Health and Human Services saying the buses won't arrive Tuesday. [boldface added for emphasis]
The phrase "as previously scheduled Tuesday" is tacked on to the end of the first sentence. I suppose it could be argued that the words aren't directly attributed to Grijalva in the sentence, that they could have been added by the reporter for elaboration, but the sentence leaves the impression those words came from Grijalva.
That means, according to what I have read, the only person who claims to have inside information about buses coming to Oracle is Pinal County Sheriff Paul Babeu.
