Michelle Obama expressed her concern over the immigration policies implemented by President Trump's administration, particularly the increased rates of deportation, during a 2019 event at the Obama Foundation Summit in Chicago. She mentioned that these issues were causing her to lose sleep as they affected real people and families in the United States.

Her comments were made in the context of the ongoing debate surrounding immigration in the United States and the Trump administration's actions, such as the "zero tolerance" policy that led to the separation of migrant families at the US-Mexico border and the subsequent detention of thousands of children. This policy faced widespread criticism for its impact on vulnerable populations and the treatment of those seeking asylum.

Michelle Obama's statements highlighted the human cost of such policies and emphasized the need for compassion and understanding in addressing the complex issue of immigration. She did not specifically use the term "deportations" in the quote that was widely reported, but rather talked about the broader issue of the Trump administration's immigration actions that were causing distress and anxiety among affected communities.
