Prompt
A realistic portrait of John O. Brennan, a middle-aged man with a serious expression, wearing a suit and tie, with a subtle hint of a smile. He should be depicted in a formal, professional setting, possibly with a subtle background that suggests his connection to the White House or the Central Intelligence Agency. The style should be photorealistic, with attention to detail and texture. The image should convey a sense of authority, intelligence, and gravitas, reflecting his role as a high-ranking intelligence officer and government official.
