TALLAHASSEE, Florida (AP) — A snapshot of where Florida Sen. Marco Rubio stands on issues likely to be debated during the Republican presidential primaries, as he enters the race.

IMMIGRATION

Rubio, whose parents emigrated from Cuba, was a co-author of a bipartisan immigration overhaul that would have provided a pathway to citizenship for immigrants in the U.S. illegally. Rubio backed off the issue, after the measure came under fire from conservatives.

Rubio now says that border security must be improved first, followed by revamping the process used to allow people to immigrate. He criticized the Obama administration's executive actions on immigration, saying the president has exceeded his constitutional power.

___

FOREIGN POLICY

Rubio has been a consistent critic of Obama's foreign policy efforts, including the president's dealings with Latin American countries. Rubio has been a leading critic of Obama's decision to restore diplomatic ties to Cuba and called it a "victory for oppressive governments."

He was among 47 senators who signed a letter warning that Congress could upend a deal being worked out by the U.S., Iran and others to control Tehran's nuclear program.

___

BUDGETS AND ENTITLEMENTS

Rubio, like many Republicans, has called for the repeal of Obama's health care law. Although he's criticized the growth of entitlement programs, he has called for increasing military spending.

Last year, he proposed a dramatic overhaul of the nation's anti-poverty programs. The proposal called for placing most of the programs into one central agency that would then hand out grants to states, which would design their own programs.

SOCIAL ISSUES

Rubio has consistently supported abortion restrictions. In 2013 he was co-sponsor of a bill that would have banned abortions 20 weeks after fertilization, but included exceptions for rape, incest and to save the life of the woman.

Rubio said decisions whether to allow same-sex marriage should be left to states.

He opposed a medical marijuana initiative that was on the 2014 ballot in his home state, but he did support legislation in Florida that authorized the limited use of a non-euphoric strain of the drug.

___

CLIMATE CHANGE

Rubio has acknowledged that the climate is changing, but he has expressed skepticism that it is being caused by human activity. He has also said that the threat of climate change does not justify pursuing policies that he contends would harm the economy.
