Krish O'Mara Vignarajah

In June 2020, Vignarajah went public with her breast cancer diagnosis. In an interview with The Baltimore Sun, she said, "My hope is to do my part to lift some of the stigma and anxiety that sits around breast cancer."

In 2019, she became president and CEO of the Lutheran Immigration and Refugee Service. During her tenure there, the refugee resettlement agency filed litigation against the Trump administration, challenging the legality of Executive Order 13888, which seeks to give state and local officials the authority to opt out of refugee resettlement in their jurisdictions. In an interview with NPR, Vignarajah described the policy as "cruel and shortsighted," and noted that "refugees that have been waiting to be reunited with their families for years may be forced to settle hundreds of miles away." Vignarajah also spoke out against the Executive Order in a Baltimore Sun OpEd entitled, "The courts should declare Trump's refugee order unconstitutional." The lawsuit has thus far resulted in a preliminary injunction against the policy, barring its implementation temporarily. In response, Vignarajah told NBC News, "This injunction provides critical relief. Those who have been waiting for years to reunite with their families and friends will no longer have to choose between their loved ones and the resettlement services that are so critical in their first months as new Americans."

Vignarajah ran for governor of Maryland in the 2018 primary election, finishing fourth. She gained "some national attention" because had she won, "she would have been the first woman, immigrant or person of color to be elected governor in the state".

The second child of Elyathamby and Sothy Vignarajah, Krishanti Vignarajah has been called a prominent Maryland resident, and one of Maryland's "Top 100 Women" and "Top 50 Influential Marylanders" by The Daily Record. She and her brother Thiru Vignarajah arrived in the United States as young children when their parents fled civil war in Sri Lanka. At Yale College she earned a B.S. in Molecular, Cellular and Developmental Biology, graduating magna cum laude and with Phi Beta Kappa honors; she also earned a Master's degree there in Political Science. She was a 2002 Marshall Scholar at the University of Oxford, where she received an M.Phil. in International Relations. She returned to Yale Law School, where she served on the Yale Law Journal.

Krishanti O'Mara Vignarajah (born 1979) is a Marshall Scholar and an immigration advocate serving as President and CEO of Lutheran Immigration and Refugee Service. Previously, Vignarajah served as Policy Director to former First Lady Michelle Obama.
