(CNSNews.com) - Speaking at a rally in Harrisburg, Pa., on Saturday night, President Donald Trump repeatedly told a crowd of supporters that he is going to fulfill his campaign commitment to build a wall on the U.S.-Mexico border.

His re-statement of this position was met with a chant from the audience: “Build that wall! Build that wall! Build that wall!”

Trump started the section of his speech on immigration by telling the crowd that: “Perhaps in no area have past governments sold out to special interests and foreign lobbyists more than on the issue of immigration.”

“Don’t worry, we’re going to have the wall,” Trump said. “Don’t worry about it.”

A few moments later, Trump repeated his vow on the wall—and criticized politicians who oppose it.

“And many people are now talking, as I just said, and using this tremendous early progress on the border to say we don’t need the kind of safety that we really do need—including the wall,” said Trump. “We need safety. We need cameras. We need all of things that we are going to be putting in. But we need the wall. And we will build the wall as sure as you are standing there tonight. We need the wall.”

At this point, the crowd started chanting again: “Build that wall! Build that wall! Build that wall.”

“We’ll build the wall, folks,” Trump said. “Don’t even worry about it. Go to sleep. Go home, go to sleep, test assured. That’s the final thing we needed. We need it.

“And if the Democrats knew what the hell they were doing they would approve it so easy because we want to stop crime in our country,” said Trump. “Obviously, they don’t mind illegals coming in. They don’t mind drugs pouring in. They don’t mind, excuse me, MS-13 coming in. We are getting them all out of here.”

Trump was speaking the day after he signed the first federal spending law of his new administration. The law extends for one week the CR that President Barack Obama signed in December. It permits funding of Planned Parenthood, but does not fund the border wall. By this Friday, Congress must pass yet another spending bill.

Here is an excerpt from Trump’s speech in Harrisburg:

Trump: Perhaps in no area have past governments sold out to special interests and foreign lobbyists more than on the issue of immigration. Year after year, you’ve pleaded for Washington to enforce our laws as illegal immigration surged, refugees flooded in and lax vetting threatened your families safety and security.

Your pleas have finally been--

Oh, don’t worry, we’re going to have the wall. Don’t worry about it.

Crowd: Build that wall! Build that wall! Build that wall! Build that wall!

Trump: We’ve done so well at the border a lot of people are saying: Oh, wow, maybe the president doesn’t need the wall. We need the wall to stop the drugs and the human trafficking. We need the wall. In just 100 days we have taken historic steps to secure our border. Imposed needed immigration control like you’ve never seen before. Is that true? And properly screened and vet those seeking to come into our country as you have never seen before seeking admission into our country. They are going to come in because they love our country, we are not taking them otherwise. We are operating on a very simple principle: That our immigration system should put the needs of American workers, American families, American companies and American citizens first.

I appointed a great military general, John Kelly, to lead the Department of Homeland Security. Since my election, we have already achieved an unprecedented 73 percent reduction in illegal crossings on our southern border, the greatest reduction in the history of our country and we just started. The world is getting the message: If you try to illegally enter the United States, you will be caught, detained, deported or put in prison. And it will happen.

As I campaigned across the nation, I met with the grieving mothers and fathers of children, who had been killed, viciously killed, violently killed by illegal immigrants. And I made them a promise: We will protect American lives. Your family member will not have died in vain...

…And many people are now talking, as I just said, and using this tremendous early progress on the border to say we don’t need the kind of safety that we really do need—including the wall. We need safety. We need cameras. We need all of things that we are going to be putting in. But we need the wall. And we will build the wall as sure as you are standing there tonight. We need the wall.

Crowd: Build that wall! Build that wall! Build that wall:

Trump: We’ll build the wall, folks. Don’t even worry about it. Go to sleep. Go home, go to sleep, test assured. That’s the final thing we needed. We need it. And if the Democrats knew what the hell they were doing they would approve it so easy because we want to stop crime in our country. Obviously, they don’t mind illegals coming in. They don’t mind drugs pouring in. They don’t mind, excuse me, MS-13 coming in. We are getting them all out of here.
