Daniel Inouye, the longtime Hawaii senator, a decorated World War II hero, died Monday of respiratory complications at Walter Reid National Military Medical Center at age 88.

“Senator Inouye deeply understood the importance of the U.S.-Israel relationship, and as chairman of the Appropriations Committee, worked tirelessly and effectively to ensure that America’s ally, Israel, had the necessary resources to defend her people,” the American Israel Public Affairs Committee said in a statement. “He will be missed by all who appreciated his many decades of leadership in strengthening the ties between America and Israel.”

Inouye enlisted in 1943 as soon as a ban on Japanese Americans serving in the army was lifted. He lost his arm in Italy in 1945, but persisted in leading on an assault a ridge heavily manned by German troops, an act that won him the Medal of Honor “for conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty.”

Recovering in a hospital, he heard from a fellow patient about his discovering bodies killed in ovens at a camp liberated by U.S. forces.

Recounting the memory as recently as October, to students in a high school in Jerusalem, Inouye said he asked his fellow patient what their crime could have been. He was told “they were Jews,” and the answer changed his life, the Jerusalem Post reported.

Inouye’s first job was selling Israel Bonds in Hawaii, and he considered converting to Judaism, but pulled back, worried that his devoutly Christian mother would be upset.

Inouye, first elected to the U.S. Senate in 1962, rose to become its lead Democratic appropriator. He enjoyed a convivial relationship with Ted Stevens of Alaska, for years his Republican counterpart.

“We mourn the discourse that belonged to these two but seems to be evaporating,” Rabbi Levi Shemtov, who directs American Friends of Lubavitch, told JTA.

Pro-Israel Republicans and Democrats mourned his passing on social media. The National Jewish Democratic Council called Inouye “a true mensch in every sense of the word.”

Inouye was a lead sponsor of the legislation in the mid 1990s that recognized Jerusalem as Israel’s capital. His role as a lead appropriator helped guarantee U.S. defense assistance to Israel.

“Our people owe him an immense historic debt,” Michael Oren, the Israeli ambassador to Washington, said in a statement. “The Iron Dome system that recently intercepted hundreds of terrorist rockets aimed at our homes stands as enduring proof of his commitment to the defense of the Jewish State.”

In honor of the annual White House Hanukkah celebration, Rabbi Levi Shemtov, Director of American Friends of Lubavitch,  kashered the White House kitchen.  Shemtov – with the help of the White House kitchen staff and Chef Tommy Kurpradit, prepared the White House to host 550 guests for the annual celebration.

The  first conducted by President George W. Bush in 2001.

Israeli Ambassador Michael Oren, members of the House of Representantives and Senate, Supreme Court Justices, rabbis,  artists, astronauts, members of the military, Democratic activists and donors gathered in anticipation of Hanukkah at the White House on December 8, enjoying traditional foods such as latkes, jelly doughnuts and smoked salmon as well as new Jewish favorites such as sushi.

Guests were treated to a jazz rendition of “Rock of Ages” and a musical tribute to Jewish-American Composers by the U.S. Marine Chamber Orchestra and lit a Chanukah menorah – a little early – which had been salvaged from a synagogue ravaged by Hurricane Katrina.

President Jimmy Carter was the first to recognize Hanukkah, when he lit the National Menorah in Lafayette Park erected by Chabad-Lubavitch.  The first Hanukkah lighting ceremony at the White House was conducted by President William J. Clinton.
