Trump reviews new section of Wall on US Southern border

"It looks great, it's better and much more effective than the previous wall," Trump said on Friday. "We actually can do it faster. It's less expensive if you can believe it. So it's better, faster and less expensive. It's a great stretch of wall."

Trump toured the new 30-foot, 2.25 mile-long border wall that replaced old fencing made of landing mats from the Vietnam War.

Local US border patrol agents and sheriffs discussed with Trump some of the challenges they face to secure their sections of the US-Mexico border.

Trump in response to questions from reporters said he will impose tariffs on Mexican cars and close the southern border if Mexico does not do enough to stop illegal migration heading to the United States. However, he also thanked the Mexican government for recent efforts to help deter the flow of migrants coming to the United States.

Trump declared a national emergency last month to free up to $8 billion in federal funding to build a wall on the US southern border. The president has said the wall is needed to prevent criminals and terrorists from pouring into the United States. Congress passed a resolution to terminate Trump's border emergency declaration, but the president signed his first-ever veto to overturn the legislation.
