Watch President Obama Deliver the 2015 State of the Union [VIDEO]

Tuesday night, President Obama will delivered the State of the Union address from the floor of the House of Representatives in Washington. It was his sixth such message, the first before a Republican-controlled Congress, following the GOP's victories in the 2014 midterms.

The president was expected to introduce several new tax proposals, following up on his recent push for free community-college education, and announce further plans to address climate change, problems with the country's immigration system and possibly the upcoming Supreme Court case on the Affordable Care Act (aka Obamacare), among other topics.

The White House has set up an information page on the State of the Union, containing links to issues the speech will cover and offering ways to engage with the material. The Republican response was given by newly elected Senator Joni Ersnt, of Iowa, soon after the president finishes.
