AUSTIN, Texas (AP) — Former GOP presidential candidate Ron Paul posted a picture of himself in a hospital Friday but said he was OK after video circulated online of him struggling to speak during an interview. The 85-year-old former Texas congressman, who ran for president three times, posted a picture on Facebook showing him smiling in a hospital gown and giving a thumbs-up. “I am doing fine. Thank you for your concern,” he said. The post came after a video took off on social media showing Paul having trouble speaking during an appearance on his livestreamed show “Ron Paul Liberty Report.” The video cuts away to the interviewer as Paul struggles. Paul is the father of Sen. Rand Paul, R-Ky., whose office did not immediately return a message Friday.
