"Think about the sheer audacity of Mr. Spicer to say that to my face with a smile, knowing that he that he is being recorded on video and the position of power he holds in our government", Chauhan, an Indian-American, said in her post of Spicer's comment. "Have you committed treason, just like the president?" she asked Spicer. "Nothing found. This is McCarthyism", he wrote.
"This way, it is the American people who will profit", she said.
She called Trump's alleged ties to Vladimir Putin's Russian Federation as "bigger than Watergate".
With Spicer's latest 'splaining, it sounds like the White House is sticking to its story that surveillance was done but is walking back the charge that Obama was directly involved. "The way that we can avoid scrutiny is to let the press corp determine where it should go", White House spokesman Sean Spicer told media at the White House briefing, prompting laughter from reporters in the room. "It is numerous same outlets in this room that talked about the activities that were going on back then". He also said the president wasn't using the term wiretapping literally in his provocative March 4 tweets and was instead broadly referring to surveillance.
While intelligence agencies have reportedly intercepted communications between the Trump campaign and Russian officials through an investigation into Russian attempts to interfere in the United States election, no credible mainstream news outlets have reported that Obama or his administration conducted surveillance on Trump or the campaign.
Chauhan streamed the encounter live on Periscope and The New York Post excerpted parts of her exchange.
During a video question and answer session with Twitter users in September 2015, Trump responded to an inquiry asking whether he would take a salary.
White House counselor Kellyanne Conway also addressed the wiretapping claims in an interview Sunday with the Bergen County Record, suggesting that other covert surveillance methods used by the Central Intelligence Agency - as revealed by Wikileaks last week - could have been used in Trump Tower by the Obama administration.
"Only one article, with British roots [the Heat Street piece, which was written by a British journalist], reported that a FISA court order was granted in October to examine possible activity between two Russian banks and a computer server in the Trump Tower", the Post reported.
She highlighted Trump's divisive immigration policies including the banning of travellers from six-Muslim majority countries.
Trump has frequently come under fire for overstating his giving. "Moreover, they also do not back up the administration's revised claim of politically motivated investigations".
McCain was one of several top lawmakers in Congress to call on Trump to provide evidence of his unsubstantiated claim.
In short, there weren't "numerous reports from a variety of outlets" about Obama-directed wiretaps at Trump Tower.
