Back in 2013 Democratic Senators such as Chuck Schumer, Mazie Hirono, and Elizabeth Warren voted yes to protect the border along the United States and Mexico in a bipartisan effort in immigration reform. Included was about 700 miles of fencing along the border and efforts to end chain migration and the visa lottery.
Flash forward to 2019 and these same type of Democrats are no longer supporting immigration reform strategies proposed by President Donald Trump.
People want to know what changed.
In 2013, the effort was basically led by then-Senate Minority Leader Chuck Schumer in which 52 Democrats and two independents were satisfied enough to say OK to the proposed legislation.
These folks voted yes on immigration reform in 2013.
