It was the second time this month that former Sen. Bob Dole has visited his old haunt.

Earlier in December, the 89-year-old Kansas Republican came to the Senate floor in a wheelchair to implore his colleagues to vote for a United Nations disability rights treaty.

On Thursday afternoon, he walked half the length of the Rotunda and back to say goodbye to an old friend.

The memorial service for Sen. Daniel K. Inouye, D-Hawaii, took place in the morning with eulogies from Senate Majority Leader Harry Reid, D-Nev., Speaker John A. Boehner, R-Ohio, and Vice President Joseph R. Biden, Jr.

Inouye, the second-longest-serving senator in history, died Monday at the age of 88. He will lie in state at the center of the Rotunda, his casket draped with the American flag, until Friday morning, when he will be transported for another service at the National Cathedral.
