McConnell froze in front of cameras for the second time in as many months raising questions about whether the GOP leader could continue to hold his powerful position atop the Senate GOP Conference . After he froze last week in Covington Kentucky McConnell was evaluated by four neurologists according to a person familiar with the matter . McConnell suffered a concussion and broken ribs after falling at a Washington hotel and hitting his head in March sidelining him from the Senate for nearly six weeks . The Republican leaders office had attributed the two frozen moments to lightheadedness and Monahan had indicated in a previous letter that its not uncommon for victims of concussion to feel lightheaded . There is no evidence that you have a seizure disorder or that you experienced a stroke TIA or movement disorder such as Parkinsons disease the letter said . McConnell is expected to continue to stay through this Congress as leader but there are growing questions about if he will continue to serve in the next Congress which begins in January . The note comes as the Senate returns to session Tuesday after a fiveweek recess and as GOP senators are expected to face questions over whether they believe the Republican leader can continue to lead their conference as he has for the past years longer than any party leader in Senate history . McConnell says August was a ‘busy and productive month for me and my staff back in the Commonwealth he said in his remarks . McConnell detailed events he attended during the recess pausing once to take a drink of water. He said August was to take away from the recess to take out a few weeks to take some of his own time to take his own personal life. The note. s Kristin Wilson contributed to this report.
