Arizona Sen. John McCain was diagnosed with a brain tumor, the Mayo Clinic Hospital in Phoenix announced on Wednesday.

 
 

"Further consultations with Senator McCain's Mayo Clinic care team will indicate when he will return to the United States Senate," his office said in a statement.

The announcement follows a procedure that McCain, 80, had on July 14 in which a blood clot was removed from above his left eye.
