We grieve the loss of any life as a result of the toxicity, the devastation... The challenge of fentanyl is not new. It has been escalating for more than five years.... This is a scourge and all of us have to work together to combat...

I stand by my statement...that China does bear responsibility because many of the precursor chemicals and the pill press equipment that is used to manufacture fentanyl does originate from there. This is a complex problem. We are taking it to the criminals..."

I see other countries with systems that are more advanced than ours that can match the need for labor with the supply for labor... It is proven that lawful labor pathways cause a reduction in the number of irregular arrivals at our border..."

We have used our parole authority consistent with the law and consistent with past practices of different administration."
