GOP President George H.W. Bush signed program into law that Trump is blaming Schumer for. [View all]
Schumer was a junior senator at the time of the signing of the law (1990), which had bipartisan support.
More from the WA Post:
Congress approved the Diversity Visa Lottery, also known as the green card lottery, as part of the Immigration Act of 1990, but it didnt take effect until 1995.
Under the program, the State Department offers 50,000 visas to each year to immigrants from parts of the world with relatively low immigration rates over the previous five years. Most visas go to people from African nations, as The Washington Post has reported.
To qualify, applicants must have a high school education or two years in an occupation in that requires formal training. Those who meet eligibility requirements are selected at random from a computer lottery. The State Department refers to them as diversity immigrants.
On Edit: As exboyfil posted below, McConnell, Hatch, and Grassley also voted "yes" for this program in 1990.
