US President Donald Trump has set out new plans on his Mexican wall project to try to end a partial government shutdown lasting more than four weeks.
One of his “compromises” was on so-called Dreamers – who entered the US illegally when young. He still wants $5.7bn (£4.5bn) to fund the wall.
Democrats have refused to fund it and ahead of the speech had already rejected the expected concessions.
The shutdown, the longest in history, has affected 800,000 federal workers.
The president had himself trailed the speech as an “important announcement”.
He started by saying the US had a proud history of welcoming new legal migrants, but that the immigration system had been “badly broken for a very long time”.
Mr Trump said that in his election campaign he had pledged to fix the system and “I intend to keep that promise”.
He said he was “here to break the logjam and provide Congress with a path forward to end the government shutdown”.
He again spelled out his reasons for building the wall and again stressed it was not a continuous structure, just one of steel barriers in high-priority areas. But the demand for $5.7bn to fund it remains.
The two new ideas concerned the Dreamers and Temporary Protection Status (TPS) holders.
There are some 700,000 Dreamers, who were young when they entered the United States with their parents illegally,
The Dreamers are currently protected from deportation under a programme that allows them to work but not get citizenship. It is a programme Mr Trump has been trying to rescind.
But he said he would extend protection for Dreamers for another three years, allowing them continued access to work permits.
He said he would also extend the visas for TPS holders for three years. More than 300,000 people from countries affected by war or disasters are allowed to work in the US under TPS, another system Mr Trump has opposed.
There were other proposals, including $800m in urgent humanitarian assistance, 2,750 more border agents and security officials and 75 new immigration judge teams. Certainly the latter conforms largely with Democrat suggestions.
The president said his proposals were “reasonable with lots of compromise” and would “build trust and goodwill”.
Democratic House Speaker Nancy Pelosi issued a statement based on the main expected concessions on Dreamers and TPS.
It read: “Unfortunately, initial reports make clear that his proposal is a compilation of several previously rejected initiatives, each of which is unacceptable and in total, do not represent a good faith effort to restore certainty to people’s lives.”
The statement continued: “It is unlikely that any one of these provisions alone would pass the House, and taken together, they are a non-starter,”
Other key Democrats also rejected the plans before they were proposed, sticking by the party’s position that it will not negotiate until government is reopened.
Democratic Senator Chuck Schumer issued a statement saying that Mr Trump had “single-handedly” taken away Dreamer and TPS protections and that offering some protections back was “not a compromise but more hostage taking”.
Opinion polls still suggest more people blame Mr Trump for the shutdown than the Democrats.
Some of the 800,000 federal employees who have been going unpaid since 22 December are in increasingly dire straits.
More than 1,500 appeals have been set up by them on crowdfunding site GoFundMe, seeking a financial lifeline to pay rent or feed and clothe their children.
In desperation, the Department of Agriculture, the Internal Revenue Service and the Federal Aviation Administration have just recalled more than 50,000 employees, who must work without pay.
