They will be watching Trump's speech closely.
Will Trump stay on script?
"I think that part of the goal with this speech is to try to get the American public to think of his first year as a success", Mercieca says, "and so that would require projecting a lot of optimism". Or go straight to Twitter and watch it here.
The Sun-Times also reported that Democratic Reps. "This is a good speech to set a new tone".
"We hope the president focuses on economic growth and accomplishments and leaves out the drama", said Republican strategist Scott Reed.
Democrats, meanwhile, are expected to use the event as a platform to speak out against the president's policies - like immigration - or to bring attention to other high-profile issues, like sexual harassment. "I just can not do it", he added. "Republicans may end up pointing to the repeal of the individual mandate as the repeal of the law as a whole".
As for immigration, he will likely address the framework his administration released last week that includes a path to citizenship for Dreamers in exchange for border wall funding.More news: Brutal photo shows Hyeon Chung's Australian Open injury
Trump has complicated negotiations by shifting his position.
The President will talk about the North Korean threat in a "strong and serious way", the source said.
Trump will also promote a $1.7 trillion plan to rebuild America's aging roads and other infrastructure, but he is not expected to offer many details.
Trump's senior adviser Stephen Miller is in charge of writing the speech.
The White House says that it is fully cooperating with special counsel Robert Mueller's ongoing investigation, so much so that Trump himself agreed to be interviewed - repeatedly insisting that his campaign did not collude with Russian Federation to sway the 2016 election. Trump has denied any collusion with Russian Federation and has called the Mueller's investigation a "witch hunt" and "hoax".
Trump makes the trip down Pennsylvania Avenue to Capitol Hill at a time when the Russian Federation investigation appears to be intensifying, and a day after the deputy director of the FBI stepped down amid increasing Republican criticism of the Mueller investigation.
USA intelligence agencies have concluded that Russian Federation interfered in the campaign using hacking and propaganda to attempt to tilt the race in favor of Trump. Though the trajectory of lower unemployment and higher growth began under his predecessor, Trump argues that the tax overhaul he signed into law late previous year has boosted business confidence and will lead companies to reinvest in the United States.
