GITMO never closed because the US didn't find countries super willing to take in the detainees, and felt it would be "too distasteful" to let them stay in the US proper. Not a good case for violating human rights law, IMO, but to quote POTUS "it is what it is."
1993, 1994, 1995, Clinton was President and the House and Senate were both Democratic. Clinton's big immigration reform bill was the Illegal Immigration Reform and Immigrant Responsibility Act of 1996. It's purpose was to "[strengthen] the rule of law by cracking down on illegal immigration at the border, in the workplace, and in the criminal justice system — without punishing those living in the United States legally."
Clinton created the mass-deportation machine in use today. Clinton's bill made it harder to immigrate to the US. Clinton created the 3-year and 10-year re-entry bars that continue to separate loved ones to this day. If an unlawful resident marries a US citizen, they're entitled to a green card but they can't apply for it from within the US but as the minute they leave they get a 10-year re-entry bar.
The last guy to grant amnesty to the undocumented was Reagan in 1986, and he was, last I checked, a Republican.
At some point you've gotta stop blaming the other guy.
Democrats are not the party of immigration, legal or illegal.
