The President's hesitation comes as the administration faces heat from Republicans and Democrats for its handling of an influx of migrants at the US-Mexico border. But the situation at the US southern border is separate from the refugee program, which dates back decades and has a thorough vetting process in place for refugees overseas to resettle in the US... The delay resulted in the cancellation of hundreds of refugee flights and left thousands of people expecting to arrive in the US after a years-long process in limbo. Mark Hetfield, the president and CEO of HIAS, a refugee resettlement organization, shared the story of one nearly 30-year-old Congolese woman who had been vetted and approved to fly to the US in early March. When Biden's signature didn't come, her ticket was canceled, and because she is now in her third trimester, she can no longer travel.
