ST. LOUIS, MO (KTVI) – The widow of murdered St. Louis County Police Officer Blake Snyder is headed to Washington DC. Elizabeth Snyder posted to Facebook last week that she has been invited to sit in house chambers Tuesday for President Trump’s address to congress.

Snyder says she’s honored and cannot wait to find out what the President has in store, especially for law enforcement.

Elizabeth Snyder writes in a post to Facebook:

“A week from tomorrow President Trump will be addressing congress with an idea of his agenda and what he plans on doing for this nation. I have been invited to sit in on the address in D.C. in the House of Chambers. I’m completely honored and cannot wait to hear what our President has in store, especially for Law Enforcement. I encourage everyone to watch it live as it will be televised next Tuesday evening.”

President Donald Trump is set to give an address to a joint session of Congress on Tuesday — but it technically won’t be his first State of the Union address.

Trump isn’t shaking up any traditions — as he is known to do — but instead following what past presidents have done before him. His speech will be known as an “address to a joint session.”

Traditionally, a president of the United States should be in office for a year before they give their first State of the Union address.

In a State of the Union address, the president usually reflects back on the past year and how the nation is doing, as well as uses the opportunity to highlight the administration’s legislative agenda — which needs congressional support — and priorities for the country.

The Constitution states that the president “shall from time to time give to the Congress information of the State of the Union, and recommend to their consideration such measures as he shall judge necessary and expedient.”

However, it is expected that Trump will use Tuesday’s speech to continue outlining his goals for the his administration.

President George Washington was the first to deliver a regular address before a joint session of Congress in New York in 1790.

The message used to be known as “the President’s Annual Message to Congress,” until President Franklin D. Roosevelt referred to it as the “Annual Message to Congress on the State of the Union” in 1934.

It began to be informally called the “State of the Union” message or address from 1942 to 1946, and since 1947, it has officially been known as the State of the Union Address.

Trump’s speech is set for Tuesday at 9 p.m. ET.
