Here's a link to the bill she cosponsored to create an amnesty for illegal agricultural workers in 2003-2004 http://thomas.loc.gov/cgi-bin/bdquery/z?d108:HR03142:@@@L&summ2=m&
Yes, but has the bill become law?
She also voted for or co-sponsored other provisions against illegal immigration as well.
Like I said, her record on immigration is very mediocre, which can be changed through pressure. Nelson doesn't give a feces about phone calls from conservatives and will vote 100% amnesty.
