If you're pining for the days when there was a primary debate on TV every other week, Wednesday is your night. Sen. John McCain, R-Ariz., and Sen. Lindsey Graham, R-S.C., were set to appear on CNN for a town hall event at 9 p.m. EST.

Dana Bash was scheduled to moderate the conversation, which was expected to last an hour and center around the country's "place on the world stage, U.S. Russian policy, immigration and other national security issues facing Americans at home," according to a news release.

McCain and Graham have been increasingly vocal in recent weeks about their disagreements with President Donald Trump. For example, McCain, the 2008 Republican nominee for president, and Graham, who dropped out of the 2016 race before the Iowa caucuses, made headlines in January when they took issue with Trump's travel ban temporarily forbidding people from seven Muslim-majority countries from entering the United Staes.

The duo issued a joint statement condemning Trump's executive order.

"Our government has a responsibility to defend our borders, but we must do so in a way that makes us safer and upholds all that is decent and exceptional about our nation," they said. "Our most important allies in the fight against ISIL are the vast majority of Muslims who reject its apocalyptic ideology of hatred. This executive order sends a signal, intended or not, that America does not want Muslims coming into our country. That is why we fear this executive order may do more to help terrorist recruitment than improve our security."

Trump fired back in a tweetstorm, saying that the statement itself was "wrong" and the men were "sadly weak on immigration."

"Senators should focus their energies on ISIS, illegal immigration and border security instead of always looking to start World War III," the president wrote.

Wednesday's town hall was taking place at George Washington University, but it wasn't the only such event Graham had on his schedule for the week. On Saturday, Graham will have a town hall on his own in Clemson, South Carolina, according to the Greenville Journal.
