Tamera Stanton Luzzatto, the chief of staff to Senator Hillary Rodham Clinton of New York, and David J. Leiter, who was appointed to an Energy Department post in President Bill Clinton's administration, were married yesterday in New York. The bride's father, the Rev. Norman D. Stanton of Hartsdale, N.Y., a Presbyterian minister, performed the ceremony at the Madison Avenue Presbyterian Church.

Hilton’s second claim — that a Kerry associate paid off Democratic senators to orchestrate the transfer of money to Burisma — is also unsubstantiated.

What’s true is that David Leiter, a lobbyist hired in 2014 by Burisma, served as Kerry’s chief of staff for seven years while Kerry was a senator for Massachusetts. Kerry spokesman Matt Summers said Leiter left the office in 1997, 16 years before Kerry became secretary of state.

Remember Devon Archer, Hunter Biden's business partner? He had previously been a top fundraiser for John Kerry, who was Secretary of State at the time. And soon after Devon and Hunter joined the Burisma Board, the company channeled $90,000 to a lobbying firm called ML Strategies, which was headed by none other than David Leiter, John Kerry's former chief of staff.

That's handy because then-Secretary of State John Kerry himself has visited Ukraine with promises of U.S. aid and assistance. Well, Leiter registered as a Burisma lobbyist in mid-2014. But in the year leading up to that, he gave close to $60,000 to Democrats, including a select group of U.S. senators who would later be instrumental in pushing cash towards Ukraine's energy sector, directly in line with Burisma's interests.

According to a report from Time Magazine in July 2014 –

David Leiter, a former Senate chief of staff to Secretary of State John Kerry, signed on to work as a lobbyist for Burisma on May 20, 2014, about a week after Biden announced he was joining the company, according to lobbying disclosures filed this month.

Leiter’s involvement in the firm rounds out a power-packed team of politically-connected Americans that also includes a second new board member, Devon Archer, a Democratic bundler and former adviser to John Kerry’s 2004 presidential campaign. Both Archer and Hunter Biden have worked as business partners with Kerry’s son-in-law, Christopher Heinz, the founding partner of Rosemont Capital, a private-equity company.
