Story highlights Israeli Prime Minister Benjamin Netanyahu met Donald Trump and Hillary Clinton on Sunday

The meetings were arranged over the past few days

(CNN) Israeli Prime Minister Benjamin Netanyahu met Hillary Clinton Sunday night at a New York hotel, after conferring earlier in the day with Donald Trump for nearly 90 minutes at Trump Tower.

Clinton, the Democratic nominee, talked with Netanyahu during a closed-door meeting at the W Hotel in Union Square. It was hardly their first discussion -- the pair often held talks during Hillary Clinton's tenure as secretary of state.

Clinton and Netanyahu discussed the recently-signed U.S.-Israel defense Memorandum of Understanding to "strengthen the defense and intelligence relationship and work closely with Israel to ensure Israel's Qualitative Military Edge," according to a senior Clinton campaign aide. Clinton also stressed her commitment to countering attempts to delegitimize Israel, including through the BDS movement. That's an issue with potential to resonate with pro-Israel voters six weeks out from Election Day.

They also discussed the Iran nuclear deal -- which Netanyahu has argued against vociferously -- and other regional changes, including the ongoing civil war in Syria. Also on the table: the stalled Israeli-Palestinian peace process. "The secretary reaffirmed her commitment to work toward a two-state solution of the Israeli-Palestinian conflict negotiated directly by the parties that guarantees Israel's future as a secure and democratic Jewish state with recognized borders and provides the Palestinians with independence, sovereignty, and dignity," the aide said. Secretary Clinton reaffirmed her opposition to any attempt by outside parties to impose a solution, including by the UN Security Council."

Her meeting with the prime minister was somewhat shorter than his talk Sunday morning with Trump. Jared Kushner, Trump's son-in-law and a close adviser to his presidential campaign, and Ron Dermer, Israel's ambassador to the United States, were also on hand for the meeting, which comes the day before the first presidential debate, according to Israeli news outlet Haaretz
