Numerous national leaders are among several hundred mourners who have gathered for the funeral of longtime U.S. Sen. Richard Lugar.

Vice President Mike Pence, Chief Justice John Roberts and Senate Majority Leader Mitch McConnell all stood Wednesday as Lugar's casket was carried into St. Luke's United Methodist Church in Indianapolis.

Former Indiana Gov. Pence is expected to give a eulogy at the service, as is former Sen. Sam Nunn, the Georgia Democrat with whom Lugar spearheaded a program that dismantled thousands of former Soviet nuclear weapons after the Cold War.

Lugar served 36 years in the Senate and died last month at age 87.

The funeral procession paused outside the Indianapolis City-County Building where he was the city's mayor for eight years, and his alma mater Shortridge High School, where students lined the street.

Hundreds of mourners are expected at the funeral for Richard Lugar, the longtime U.S. senator from Indiana known for leading efforts to help the former Soviet states dismantle thousands of nuclear weapons.
