In late March of this year, Michelle Kwan reportedly saw a peculiar tweet, then a New York Daily News story, with the same message: Clay Pell, her husband of four years, had filed for divorce in the state of California. According to court documents obtained by the Providence Journal, Kwan said the pair had tried to reconcile their differences before Pell filed for divorce “without warning.”

Kwan has since filed for divorce from Pell in the state of Rhode Island, where they lived, citing irreconcilable differences, per the Journal. In the filing, Kwan says that she and Pell had started to discuss the possibility of divorce in November, and have been living in separate homes since then.

Since Pell dropped his surprise filing in March, tensions have worsened between the former couple. Pell, who wants the case to be filed in California instead of Rhode Island, reportedly did not respond when Kwan attempted to serve him with the Rhode Island divorce complaint 10 times in April.

Kwan has asked that Pell not stay in the home they are remodeling in Newport, Rhode Island. Kwan said Pell has labeled his belongings—including a mattress and suitcases—“Pell,” and they sit at their shared home. She is also asking that they both be reimbursed for the $1.5 million Newport home that they purchased in 2014, according to court documents obtained by the Journal.

The pair, married since 2013, had at least one common interest: high-powered politics. The Journal reports that Kwan, who worked on Hillary Clinton’s 2016 campaign, even rented an apartment in Brooklyn to be closer to the Clinton headquarters.

Pell made a campaign run himself, running unsuccessfully for Rhode Island governor in 2014. The lawyer also worked in the Obama White House as director of strategic planning on the national-security staff, and as deputy assistant secretary for international and foreign-language education for six months.

When he filed for divorce in March, Pell wrote the following statement, obtained then by People:

“It is with deep regret that I share that Michelle and my marriage is coming to an end,” Pell said in a statement obtained by People. “This is a sad and difficult turn of events for our family. I love Michelle, and wish her the very best as her life takes her in a new direction.”

Vanity Fair has reached out to representatives for Kwan and Pell for comment.
