What does it take to friend a U.S. senator?

If you’re Facebook, all you need is about $50,000 in donations – and a cushy job for the politician’s daughter.

Facebook employees, including some at the top of its corporate pyramid, have helped fill Schumer’s campaign coffers – and he’s returned the favor by carrying water for the social media giant in Congress, according to a recent report.

And Alison Schumer, the senator’s youngest of two daughters, works as a Facebook product marketing manager – which pays an average of $160,000, according to Glassdoor.com.

“It sure looks hinky,” political strategist Susan Del Percio told The Post. “This is an industry that’s been trying for years to fend off heavy government regulation by actively cultivating relationships with senators and House members.”

Last week, it emerged that Schumer has been a strong advocate of Facebook on Capitol Hill. He pressured Sen. Mark Warner (D- Virginia), one of Facebook’s most aggressive challengers in Congress, to back off from investigating the company, according to The New York Times.

Schumer’s support of Facebook remained steadfast even as it emerged that Russian trolls were using the social media platform to interfere with the 2016 presidential election. The company’s also come under fire for lax privacy standards leading to the exposure of users’ personal data.

“Facebook is a very powerful force,” Schumer said in March, as the problems began coming to light. “I think, overall, it’s been a very positive force.”

Top Facebook execs have contributed thousands to Schumer’s campaign fund for years.

Founder and CEO Mark Zuckerberg gave the senator $5,200 in 2013.

Sheryl Sandberg, the company’s high-profile chief operating officer, kicked in $5,400 – the maximum legal amount – to Schumer’s 2016 re-election campaign.

Facebook general counsel Colin Stretch gave the same sum in 2015.

Newly appointed board member Kenneth Chenault has been a loyal Schumer supporter since 1995. Most recently, he gave $1,200 to the senator’s 2016 primary election campaign and $2,700 in that year’s general election. Chenault has contributed a total of $6,900.

Critics have called out the cozy relationship. In April, right-leaning street artist Sabo plastered the city with posters reading “Conflict of Interest? The daughter of Chuck is working for Zuck,” The Post reported.

Alison Schumer worked for Facebook from 2011 to 2013 and rejoined the company in 2017, according to her LinkedIn profile. Schumer, who could not be reached Saturday, is set to marry Elizabeth Weiland in Brooklyn on Sunday.

“Sen. Schumer has worked aggressively to push Facebook to do more to purge fake accounts and bots used by the right wing and Russians to perpetuate a disinformation campaign and interfere with our elections,” Schumer spokesman Justin Goodman said Thursday.

But evidence of the senator’s direct efforts to grease the skids for the company could fuel Republican proposals to clamp down on Facebook.

Conservatives say the company has suppressed right-leaning news sites – LaChance’s traffic cratered by 90% after Facebook introduced a new algorithm in 2017, he said — and has banned Trump supporters unjustly.

“It will force some action,” Del Percio said. “Facebook will see a lot more aggressive questioning and oversight after this.”
