The 81-year-old Republican Senator McCain was admitted to a clinic in Arizona for diverticulitis, where he received 'the best medical care available.'
A statement was released on April 16, 2018, explaining that the Senator 'underwent surgery to treat an intestinal infection' on April 15, 2018, and that he is now recovering at this home.
As reported by CNN Edition, Senator McCain was also diagnosed with brain cancer in 2017 and was undergoing treatment in Cornville, Arizona.
Diverticulitis is the inflammation of the diverticuli in the digestive system's lining. The condition can easily be treated with medication. However, certain factors, like advanced age, could complicate matters.
Those complications could lead to severe pain, colon blockages, fistulas and infections in the abdominal cavity. Such conditions require immediate care and could prove to be fatal.
He has been receiving physical therapy to counter the side effects of the cancer diagnosis, but has 'remained engaged in his work as Chairman of the Senate Armed Services Committee.'
He is also still involved in current events, such as the Trump Administration's involvement in Syria. According to Inquisitr, McCain 'has been one of the most vocal Republican critics' of President Trump.
Earlier this month he said that the chemical attacks in Syria were partly due to Trump's statement that the US military would cease operations in Syria.
"Emboldened by American inaction, Assad has reportedly launched another chemical attack against innocent men, women, and children, this time in Douma."
