"if it was the goal of russia to create discord. they have succeeded," he wrote. "they're laughing their expletives off in moscow. the president was also critical of his national security advisor after he weighed in. >> as you can see with the fbi indictment, the evidence is now really incontrovertible and available in the public domain. >> reporter: mr. trump responded, "general mcmaster forgot to say that the results of the 2016 election were not impacted or changed." >> americans are the victims of what russia did, not republicans, not democrats. all of us are victims. >> reporter: republican congressman trey gowdy.

ago, poindexter says they were forced to let go of 70 percent of the workforce and lost about $2 million. >> they said you think it's okay to hire illegals? i said i've got a person with three american born children, u.s. citizens, and i have to fire both of their parents, both of them. >> it is a tight rope. they have to walk a fine line. >> reporter: immigration attorney angelo paparelli says this is selective prosecution. >> these recipients of notices of inspection are smaller businesses. the fact is they don't fight quite so hard. they don't have the resources for lawyers and investigators to help defend them so they can chalk up statistics. that make it impressive that they are doing something. >> reporter: rafael is here illegally and asked us to conceal his identity. his employer is also being audited and some co-workers have stopped showing up. with families and business on edge, the debate continues as to whether problems faced by many
