The stage is set for US President Donald Trump's State of the Union address on Tuesday evening.

The US Capitol in Washington DC will be packed with the country's top lawmakers, Supreme Court justices, and military leaders to hear the president's message.

Trump will address a joint session of Congress in a speech that will likely outline what he feels are the accomplishments of his first year in office and his policy agenda moving forward.

It comes ahead of the country's November midterm elections.

Lawmakers from the Senate and the House of Representatives will attend, though several Democrats have said they plan to skip it.
