Final answer:
Diane Guerrero references legislation and political actions related to immigration policy, the backlog of immigration hearings, and administrative efforts to deal with unaccompanied minors to strengthen her argument regarding contemporary immigration circumstances in the U.S.
Step-by-step explanation:
In Diane Guerrero's reference to contemporary circumstances to strengthen her argument, she underscores the legislation that has been proposed and the contentious political climate surrounding immigration policy in the United States. Specifically, she touches on the anti-immigration sentiments and legislative actions such as the construction of barriers along the U.S.-Mexico border, the failed Comprehensive Immigration Reform Act, and the sensational Arizona SB 1070 law, which sought to enforce strict immigration controls at a state level.
Guerrero also highlights the administrative efforts under the Obama and Trump administrations concerning the influx of unaccompanied minors and policies such as family separation, which received significant legal and public backlash.
The backlog of immigration hearings, despite bipartisan legislation aimed at addressing unaccompanied minors seeking asylum, and the challenges with enforcement and reception of these children and families, also feature prominently in her argument. The underlying tension between national security concerns and the push for civil rights and humane treatment of immigrants is evident in Guerrero's references, painting a complex picture of the contemporary American immigration landscape.
