Over the first six months of his administration, Donald Trump has faced increased backlash from his critics. While many liberals and independents have pushed back against the president, one of his most vocal supporters is now speaking out.

Coulter on Trump

When Donald Trump first announced that he was running for president back in June 2015, he did so with a lot of dramatics.

The consensus from the majority of the country was that he was nothing more than a joke candidate, doing so to help generate ratings on his reality show. As time moved forward, the former host of "The Apprentice" picked up steam, shocking many with his popularity. Trump was able to ride that momentum to a GOP primary victory at the Republican National Convention, before later pulling off the general election upset over Democratic nominee Hillary Clinton. While most celebrities and the media seemed to oppose Trump, he found a safe space with certain big name conservatives that went on to defend his actions at every turn.

One of Trump's loudest and loyal supporters has been conservative author Ann Coulter, who has often praised the billionaire real estate mogul for his stance on immigration and Islamic terrorism. While this was the case in the past, Coulter has expressed signs of concern over the current White House, which appeared to reach a fever pitch during a series of tweets on June 16.

Taking to her Twitter account on Friday, Ann Coulter ripped into Donald Trump for ignoring American problems, while focusing on other countries around the world, most notably his recent rollback of Obama's agenda on Cuba. "Yesterday, the Trump administration kept in place Obama’s unconstitutional executive amnesty," Coulter tweeted out.

"This daily Trump melodrama is worth it ONLY if he’s really going to build the wall, cut off Muslim refugees and deport illegals," Ann Coulter posted to her Twitter feed. "Today's BORDER WALL CONSTRUCTION UPDATE: Miles completed yesterday--Zero; Miles completed since Inauguration--Zero," she wrote in apparent frustration with the lack of progress on immigration reform.

Coulter doubles down

"Anyone in a Southwestern state who strolls to the border & drops a brick will have done more to build the wall than @realDonaldTrump," Ann Coulter added. "I thought w/ Trump we'd finally have a president helping OUR country. So far: Syria, Saudi Arabia, Israel, Italy, China, N Kor. Today: Cuba!" she wrote with increased anger.

In her final tweet as of press time, Ann Coulter continued to dig into Donald Trump, smacking down the commander in chief for not holding up to his end of bargain after promising to complete construction on a border wall between the United States and Mexico. "At least Cuba's in our hemisphere. How long can it be before Trump gets to America?" she rhetorically asked.
