Rep. Charles Rangel (D-N.Y.) wandered into the Acela lounge in Manhattan on Monday, waiting to hop on the 2 p.m. to D.C.

“Sorry you lost your colleague, Senator Lautenburg,” a woman in the lounge said to him.

“Yes,” he said, reflecting for a moment. “Guess we were a couple of dinosaurs.”

“But I am a spring chicken compared to him,” Rangel noted. “I am only 83 — he was 89!”

Lautenberg’s death leaves Sen. Dianne Feinstein (D-Calif.) as the oldest member of the Senate, though she’s only 79.

Rep. Ralph Hall (R-Texas) is the oldest House member. He just turned 90 in May.
