Recent poll numbers have been bumping up in Donald Trump’s favor following his immigration speech last Wednesday and the fallout from Democratic rival Hillary Clinton’s FBI email investigation. “The polling data that you showed earlier really tells the tale,” Trump campaign manager Kellyanne Conway told ABC’s “This Week.” “Hillary Clinton is having a hard time being accepted as a truthful and honest candidate vis-à-vis the American people.”

Clinton’s poll numbers have begun to plummet. More unraveling revelations about her use of a private email server while secretary of state, as well as connections between Clinton Foundation donors and the State Department during and after her tenure at the agency, have yet again put her in hot water.

The Trump campaign also faced repeated questions Sunday about Trump’s immigration plan. Liberal critics claim the plan is vague on the issues of deportation for illegal immigrants and whether the United States or Mexico will pay for Trump’s proposed wall along the southern U.S. border.

GOP vice-presidential nominee Gov. Mike Pence said on NBC’s “Meet the Press” that the plan begins with building the wall for border security and makes a priority of “enforcing the laws of this country.” This includes removing “criminal aliens” and people who’ve abused and overstayed their visas.

“What the American people want to see today is to establish the borders of this country, enforce the laws of this country. And Donald Trump has created a road map to do that,” said Pence. “Some 10,000 people in Arizona last week, it wasn’t the way they see it. As I travel across this country campaigning with Donald Trump and for Donald Trump, I think people hear him loud and clear. And he’s been completely consistent on this point.”
