Trump was speaking Wednesday to an audience in Pennsylvania when he included Colorado in a list of states where the border wall is being constructed, along with New Mexico and Texas.

One Democratic senator called the border wall money a "slap in the face to the members of the Armed Forces who serve our country."

Trump told a kid that the wall's being built. So far, his administration has replaced fencing that was already in place, but work could be progressing on other sections.

Kirstjen Nielsen said Monday she still shares President Donald Trump’s goal of securing the border, a day after she resigned as Homeland Security secretary.

President Donald Trump issued the first veto of his presidency on Friday, overruling Congress to protect his emergency declaration for border wall funding.

In a massive blow to Trump, the Republican-controlled Senate voted to overturn the president's emergency declaration on funding for the border wall.

Donald Trump's border wall money demand is more than six times what Congress allocated for border projects in each of the past two fiscal years.

For the first time, Trump plans to stick with the strict spending caps imposed years ago, even though lawmakers have largely avoided them with new budget deals.

Democrats controlling the House have teed up a vote next week to block President Donald Trump from using a national emergency declaration to fund a wall along the U.S.-Mexico border.

The move sets up a fight that could result in Donald Trump's first-ever veto.
