Less than a week into his presidency, Donald Trump has already acted on the promises he made to the American people, former House Speaker Newt Gingrich said.

“This inaugural rose directly out of a two-year campaign and has now led into the first week of activism,” says Newt Gingrich.

Speaking Wednesday at The Heritage Foundation for the fifth of a six-part series on understanding Trump and Trumpism, Gingrich said the president, thus far, has shown a commitment to upholding the will of the people.

According to Gingrich, Trump’s early days in the White House are just a taste of the results we can expect to see in the next four years.

“This inaugural rose directly out of a two-year campaign and has now led into the first week of activism,” he said. “What’s he focusing on—job creation, immigration, shrinking government—all the things he campaigned on. Guess what that probably means—he’s probably going to continue to do just this.”

Trump’s commitment—which helped him beat 16 Republican candidates, the elite news media, and a billion-dollar Hillary Clinton campaign—has left his critics appalled.

“Of course, it shocks all the liberals because it turns out he may actually have meant what he campaigned on, which people voted for,” Gingrich said. “That puts him so outside liberalism and outside the traditional establishment that it’s unthinkable. Therefore, it can’t be true.”

Gingrich noted the latest incident to enrage the left: Trump’s plan to launch an investigation of mass voter fraud.

“The elite media doesn’t want to cope with it, but the fact is Donald J. Trump has been saying consistently as a candidate and as a president, we have a problem with voter fraud in America,” Gingrich said.

Gingrich argued that the Democratic Party would be in “real trouble” if only legal citizens were allowed to vote.

“They can’t win in an election that only involves people who are legal citizens of the United States and alive, which I think are two reasonable criteria for being allowed to vote,” Gingrich said.

Gingrich’s remarks focused largely on the themes of Trump’s inaugural address. Gingrich said Trump’s speech was about the people, which is something Americans can continue to expect from Trump.

“What is the Trumpian revolution about?” Gingrich questioned. “It’s about the citizens joined in a great national effort, rebuilding the country and restoring its promise for all of our citizens.”

While Trump’s message was “America first,” Gingrich said Trump will “put America first within a world system.”

“If he negotiates with Mexico and when he meets with the Mexican president later on, guess what he expects the Mexican president to do,” Gingrich said. “He expects him to represent Mexico. He’s just asking for the right to represent America.”

Trump’s “moral obligation” to both God and the American people will allow him to deliver on his promises, Gingrich suggested.

“If we do what we promised to do, if we do what Trump promised in his inaugural, we would be in a fight consistently from now till either we win or they win,” he said. “That’s why this is so important.”

Gingrich will wrap up his six-part series on Trumpism at Heritage on Monday, Jan. 30. The speech will take place at 11 a.m. EST.
