U.S. Sen. Mazie Hirono is in Israel this week, part of an eight-member Democratic delegation that met with Prime Minister Benjamin Netanyahu, according to a Jerusalem Post report.

A spokesman for Hirono’s Honolulu office confirmed the trip but said little else.

The office declined to explain why Hirono is in Israel, who paid for the trip or what she hoped to learn from it. 

“We can confirm the senator is on the trip as reported, but due to security reasons we are not able to release any information until the delegation has returned to the United States,” the spokesman said. 

Further inquiries were directed to New York Sen. Kirsten Gillibrand, who is leading the delegation or “codel,” in Congress-speak.

The Post said the codel included Chris Coons of Delaware, Tammy Baldwin of Wisconsin, Tim Kaine of Virginia, Heidi Heitkamp of North Dakota, Cory Booker of New Jersey and Gary Peters of Michigan.

The newspaper described the trip as “the first group of Democratic senators to visit the country and meet the premier since the bruising battle over the Iran deal last summer.”

Israel strongly opposed the deal, calling Iran a threat to Israel’s existence. The Post noted that all of the senators supported President Barack Obama’s deal, and that none are up for re-election this year.

In related news, The Jerusalem Post reported that 16 senators have sent a letter to Obama calling for a “new and strengthened” memorandum of understanding on security assistance to Israel.

Some of the same senators visiting Israel signed the letter, but not Hirono.
