Following President Trump's explosive allegation that former President Obama wiretapped Trump Tower, there are several important questions about wiretaps and leaks, Bill O'Reilly said in his Talking Points Memo tonight.

O'Reilly pointed out that former Attorney General Loretta Lynch, working for Obama, ordered the rules about shared intelligence information be changed just days before Trump took office.

He explained that change allowed the National Security Agency to share raw information with the FBI, CIA and other intelligence agencies, creating a greater possibility of leaks.

"Why did Ms. Lynch do that? Did Mr. Obama order the change?" O'Reilly wondered. "We need to know."

O'Reilly said that information began leaking out as soon as Trump entered the White House, as his phones calls to the Mexican president, the Australian prime minister and other high-level officials were leaked to the press.

"So in effect, the Obama administration may have - I emphasize may - created chaos for the Trump administration by allowing unsubstantiated intelligence information to be spread across a number of agencies," O'Reilly said.

"This is big," he said. "If that were done to harm the incoming president, Mr. Trump, that's subversion. So you can see that Congress must get to the bottom of the situation."
