Sen. Jeff Flake offered a rare defense of President Trump on Thursday over the president's pronunciation flub of an African nation.

Trump was widely mocked Wednesday when he mispronounced Namibia as "Nambia" while praising the country's healthcare system in a speech to African leaders.

The mistake earned him headlines like "Trump praises health care of Nambia, a nonexistent African country" from CNN.

In a tweet Thursday evening, Flake, who is a vocal Republican critic of Trump's, asked people give Trump a pass on this one.

"Give @realDonaldTrump a break on Namibia. I lived there during independence. Great country, tricky pronunciation," he said.

Flake, R-Ariz., has elicited the ire of Trump in recent months, lamenting the direction the GOP has taken since Trump became president.

Last month Trump tweeted that Flake is "toxic" and "weak" on border security and crime, and praised his primary challenger, Kelli Ward.

"Great to see that Dr. Kelli Ward is running against Flake Jeff Flake, who is WEAK on borders, crime and a non-factor in Senate. He's toxic!" Trump said.
