US federal agents search home of Trump critic Omar

US federal agents searched the Washington home of Democratic Congresswoman Ilhan Omar on Monday as part of a criminal investigation, officials said.

The search was conducted by agents from Homeland Security Investigations (HSI), the investigative arm of US immigration enforcement, according to Fox News, citing sources familiar with the matter.

The operation was linked to a criminal fraud investigation concerning immigration paperwork submitted on behalf of the Somali-born congresswoman by her late father when she was a child.

Omar, 44, is a leftist Democrat and fierce critic of Trump – particularly of his administration's sweeping crackdown on immigration.

The Republican president has repeatedly clashed with Omar, who came to the United States from Somalia as a child and has frequently been the target of his political attacks.

Omar has called Trump's focus on her an "unhealthy and creepy obsession" and said she and her family have faced death threats, which she attributes to "hateful political rhetoric" especially from Trump.

No charges against Omar were announced in connection with Monday's search, but US media reported that the operation was linked to a criminal fraud investigation into immigration paperwork submitted on her behalf by her late father when she was a child.
