Congressman Rodney Davis said the Trump administration should disclose any evidence it has about the allegation President Obama ordered wiretapping of Trump campaign operations. That came in an early morning tweet from President Trump a couple weeks ago.
If there is no evidence, Davis said, Trump will have egg on his face.
"But, remember this is a President for the first time in our lifetime that has come directly from the private sector. He has a way of doing business and he believes that by tweeting it's a way to get his message to the American people. Clearly it worked during the presidential election, and he believes it is working now," said Davis.
Though the FBI has asked the Justice Department to refute Trump's allegation, Davis said if there is evidence of wiretapping without a warrant that's a huge problem.
Davis used that possibility to bolster the case for a House investigation of the allegation. Some other Republicans, though, have indicated an investigation should happen after credible evidence is proffered not before.
Davis said if there is no warrant and no evidence of wiretapping, then the President made a mistake. In that event, Davis said he hopes Trump is more careful.
If the allegation is empty, how much credibility should be given to Trump on other events?
"Well, I think it's on a case-by-case basis, and you are assuming that there is not evidence," said Davis.
Reporter: There is nothing so far and it has been going on for quite a while.
"Well, and that's why the House Intelligence Committee, in a bipartisan way, has asked for that. And the administration is going to have to give that evidence or probably lose some credibility with the American people," said Davis.
Davis said he wishes Trump would tweet less, though it has been an effective way to have his ideas reach the public.
