How does the public react when political figures state that millions of illegals workers do not compete with Americans for jobs in the US?

Do people get mad when political figures tell them that a major economic trend, like millions of illegal workers competing for jobs, is not happening? 

People do not have a chance to get angry because the mainstream media refuses to report what entities such as the Federal Reserve publish, regarding the negative effects of immigration on youth employment in the United States.

 
This is the abstract of a 2012 research paper by a Federal Reserve economist, "The Impact of Low-Skilled Immigration on the Youth Labor Market" jstor.org/stable/10.1086/662073

The employment to population rate of high school–aged youth has fallen by about 20 percentage points since the late 1980s. One potential explanation is increased competition from substitutable labor, such as immigrants. I demonstrate that the increase in the population of less educated immigrants has had a considerably more negative effect on employment outcomes for native youth than for native adults. At least two factors are at work: there is greater overlap between the jobs that youth and less educated adult immigrants traditionally do, and youth labor supply appears more responsive to immigration-induced wage changes.

The actual Federal Reserve publication was released the year prior, see Smith, Christopher L. 2011. “Polarization, Immigration, Education: What’s Behind the Dramatic Decline in Youth Employment?” Federal Reserve Board of Governors Finance and Economics Discussion Series 2011-41.
