Prompt
Generate a realistic portrait of John F. Tierney, an American politician and lawyer, in a formal setting. Depict him as a middle-aged man with a professional expression, wearing a suit and tie, likely in his congressional office or a government building. Incorporate subtle hints of his Massachusetts roots and his affiliation with the Democratic Party. The style should be photorealistic, with attention to detail and a sense of gravitas fitting for a former Member of the U.S. House of Representatives.
