Over the last week, the biggest story to dominate the news cycle has been Donald Trump and his allegations that former President Barack Obama wiretapped his office inside Trump Tower. While the White House continues to stand by Trump, some Republicans are pushing back.

McCain on Trump

After the Washington Post uncovered that current Attorney General Jeff Sessions had been in contact with Russian officials during the 2016 presidential election, the White House scrambled to shift the narrative. The growing scandal linking the Kremlin to the Trump administration has been a slow leak of controversy, and the former host of "The Apprentice" has done his best to change the narrative.

Donald Trump took to Twitter last weekend and accused Barack Obama of wiretapping Trump Tower in New York City, but has failed to provide any evidence to back up his claim. These issues, and more, were discussed during the March 12 edition of "State of the Union" on CNN.

Joining CNN host Joke Tapper was Arizona Sen. John McCain who was asked about the allegations made by Donald Trump. "President Trump has to provide the American people, not just the intelligence community, but the American people, with evidence that his predecessor, former president of the Unites States was guilty of breaking the law," McCain said.

"The president has one of two choices," John McCain continuesd.

"Either retract, or provide the information that the American people deserve." "If President Obama violated the law, we've got a serious issue here, to say the least," he added. In conclusion on the issue at hand, McCain was asked if he believed the charges were true, and he was clear in his answer. "I have no reason to believe that the charge is true," the senator said.

Moving forward

Despite the consensus among most of the mainstream media and in Washington, Donald Trump and his team are not backing down. The origins of the wiretapping conspiracy are believed to have come from an unverified article in Breitbart News, but the White House has yet to confirm. Since the allegations were made, a statement from Obama has denied the claims, labeling them "simply false."
