WASHINGTON (Reuters) – President Donald Trump on Tuesday was set to deliver a State of the Union speech challenging Democrats to approve funding for his long-sought border wall, but stopping short of declaring a national emergency over it, at least for now.

At 9 p.m. EST (0200 GMT Wednesday) before a joint session of Congress, Trump likely will stir contention with remarks on immigration policy, after his demand for $5.7 billion in wall funds triggered a historic 35-day partial government shutdown that more than half of Americans blamed him for, according to Reuters/Ipsos polling.

Millions of Americans were expected to watch the address on television, giving the Republican president his biggest opportunity to date to explain why he believes a barrier is needed on the U.S. southern border with Mexico. The speech was delayed for a week because of the shutdown, which ended on Jan. 25.

When Trump takes center stage in the chamber of the House of Representatives for the big speech, sitting behind him over his shoulder will be his main congressional adversary, Democrat Nancy Pelosi, who became House speaker after her party won control of the chamber in November’s elections.

She has shown no sign of budging from her opposition to Trump’s wall-funding demand. That has led Trump to contemplate declaring a national emergency, which he says would let him reallocate funding from elsewhere without congressional action.

A source close to Trump said the president was not expected to take that step, which likely would draw a swift court challenge from Democrats. Instead he will urge a congressional committee to work out a border security deal by Feb. 15.

“He’s going to set the stage,” the source said. “He’ll tell people, ‘Here’s why I should,’ but say, ‘I’m giving Congress another chance to act.'”

Trump continued to push his wall in a Tuesday morning tweet ahead of his evening remarks, noting that the Pentagon has sent more troops to the U.S. southern border.

“We will build a Human Wall if necessary,” he said.

WANTS DEAL FROM CONGRESS

Asked on Tuesday if Trump would use the speech to announce an emergency, White House senior adviser Kellyanne Conway said the president “has an absolute right to do it” but would prefer that lawmakers forge a solution.

“He wants Congress to finish its work and hopefully come to an agreement, put a deal on his desk that he will sign into law,” Conway told reporters at the White House.

Trump’s speech also will offer an olive branch to opponents as he looks toward the 2020 election, targeting areas he sees for potential bipartisan agreement, such as infrastructure improvements, lowering prescription drug costs and healthcare.

A senior administration official said Trump would “encourage Congress to reject the politics of resistance and retribution, and instead adopt a spirit of cooperation and compromise so we can achieve it.”

Senator Angus King, an independent, on Tuesday told MSNBC he saw potential for bipartisan action over opioids, HIV and infrastructure that could be derailed “if he throws down the gauntlet and gives us another lecture on the wall.”

Trump’s message could also be undermined by his threats to go his own way on the long-promised wall if he cannot get Congress to approve the funding he wants. He has said the wall, which he promised during his 2016 campaign and said Mexico would pay for, is needed to deter illegal immigration and drugs.

Some of Trump’s own fellow conservatives are also urging Trump not to declare an emergency. “I’m for whatever works that prevents the level of dysfunction we’ve seen on full display here the last month, and also doesn’t bring about a view on the president’s part that he needs to declare a national emergency,” Senate Majority Leader Mitch McConnell told reporters last week.

Trump also will address foreign policy, including support for an effort to coax Venezuelan President Nicolas Maduro into leaving power and declaring the Islamic State militant group all but defeated. He will also give an update on trade talks with the Chinese.

Asked if he would announce where he will next meet North Korean leader Kim Jong Un, White House spokeswoman Sarah Sanders declined to give any details in an interview with Fox News Tuesday morning.

Trump, Vice President Mike Pence and White House acting Chief of Staff Mick Mulvaney went over the speech on Monday night with about a dozen supporters including former campaign aides Corey Lewandowski and David Bossie, as well as Matt Schlapp, chairman of the American Conservative Union, a source familiar with the meeting said.

The source said Trump would discuss troop drawdowns in Syria and Afghanistan and that about half the speech would be devoted to foreign policy.

Trump also will claim success on economic policy, including cutting federal regulations, the source said.

Some Democrats have invited guests to the speech to highlight various causes, some at odds with Trump’s policies, making a raucous atmosphere possible inside the House chamber.

Representative Pramila Jayapal said on Monday she would invite climate scientist Lisa Graumlich, dean of the College of the Environment at the University of Washington, to underscore the climate change issue.

“One thing you will see is that the chamber is full and the president is surrounded by women, by people of color, by individuals who have really been hurt by this president and many of the actions that he has taken,” Jayapal said.

Republican strategist and former White House official Raj Shah said the speech offered Trump a chance to turn the page.

“Washington right now looks a little bit petty and a little bit small and the State of the Union is an opportunity to go big and talk in broad themes about what’s good about America and look beyond some of the issues of the last few weeks,” he said.
