Charles Grassley
Republican U.S. Senator from Iowa

As the longest-serving Republican in the U.S. Senate (since 1981) and chair of the Senate Judiciary Committee, Charles Grassley is a powerful voice on matters of immigration policy.
A former metal shearer and assembly-line worker from the agricultural state of Iowa, Grassley’s positions on immigration have long been shaped by the impact migrant workers have on the American workforce. According to his own website,“Grassley has worked hard to root out fraud and mismanagement of visa programs that don’t work or [that] harm the American worker.”
During the first Trump administration, Grassley was a point-man for Trump in the Senate. In February 2018, he introduced the Secure and Succeed Act, which would have provided the president with $25 billion for border security, including construction of barriers, in exchange for a pathway to citizenship for 1.8 million DACA enrollees, provided they either serve in the military or obtain a college or vocational degree and maintain employment. Grassley said this represented “a major concession for many Republicans, including me, but this concession is necessary to provide a permanent and fair solution to this issue.”
Without equivalent concessions from Democrats, Grassley has dismissed any chance of cooperating on comprehensive immigration reform. When President Biden released the first details of his proposed immigration reform bill, Grassley said, “A mass amnesty with no safeguards and no strings attached is a nonstarter.”
Beyond his work on guest-worker visas and DACA, Grassley was a strong supporter of the controversial enforcement and removal operations conducted by ICE under the first Trump administration and has advocated for an increase in the size of the agency, including “increasing agents in states like Iowa.”
After the 2024 presidential election, Grassley has shown strong support for Trump’s more aggressive approach to immigrants. On January 8, 2024, he led the Senate Republican Conference in reintroducing the Laken Riley Act, which would mandate Immigration and Customs Enforcement (ICE) to arrest, detain, and deport undocumented immigrants who commit or are charged with theft, burglary, larceny, shoplifting or other specified crimes. It would also allow states to bring civil actions against federal officials who allegedly fail to enforce immigration laws. This provision directly challenges the theory embraced in a recent Supreme Court case that the federal government has broad discretion in handling immigration issues.
Shortly after Trump’s inauguration, Grassley co-introduced, alongside Sen. Ted Cruz, the Stop Illegal Reentry Act, which would impose a mandatory minimum sentence of five years for any person who illegally enters the United States with multiple convictions, or a conviction for an aggravated felony.
