A Republican congressman on Wednesday suggested a decision this week that granted President Barack Obama's Kenyan aunt could be improper. 

Obama's aunt, Zeituni Onyango, 58, was granted asylum by a federal judge in Boston Monday. Through her attorney, Onyango, who has been living in the country illegally since 2004, said she was seeking asylum due to medical problems related to Guillain-Barre syndrome, an autoimmune disorder she says she suffers from, and because of threats of tribal violence in Kenya.

Rep. Steve King (Iowa), a conservative lawmaker who is the top GOPer on an immigration subcommittee, is skeptical. He requested that Obama and the court open records to determine whether or not the ruling was subject to bias.

“The American people deserve to know if Ms. Onyango was objectively granted asylum," he said in a statement. "No one is above the Rule of Law and we should not be granting an individual amnesty based solely on that person’s relationship to public figures. President Obama and Ms. Onyango should open the record to ensure transparency for the American people and clear any allegations of favoritism or judicial bias."

King criticized Onyango for living in the country illegally despite having been given a deportation order.

“Traditionally, asylum has been granted to those that demonstrate a well-founded fear of persecution in their home countries," he said. "A judge granted President Obama’s aunt amnesty through asylum despite her blatant disregard for the Rule of Law."
