Former U.S. President Barack Obama is no longer expected to attend the state funeral of former Prime Minister Shinzo Abe to be held later this month, U.S. and Japanese sources said Saturday.

Former U.S. Ambassador to Japan William Hagerty is set to attend the funeral slated for Sept. 27 in Tokyo as President Joe Biden's administration seeks to offer condolences through a bipartisan representative, they said.

Hagerty was among the U.S. senators who introduced a resolution honoring Abe, who was fatally shot on the Upper House election campaign trail on July 8. Hagerty became ambassador to Japan in August 2017 under the Donald Trump administration and left the post on July 2019 to run for the Senate.
