The White House and its allies in recent days have attempted to change the interpretation of Trump's explosive tweets from earlier this month.

The chairman and vice chairman of the Senate intelligence committee put out a statement on Thursday stating there is no indication Trump Tower was the subject of USA government surveillance, another blow to President Donald Trump's twitter allegations that former President Barack Obama tapped his phones.
The statement released on March 16 by Republican Chairman Richard Burr and the committee's top Democrat, Mark Warner, came one day after the leaders of the House Intelligence Committee issued a similar statement.
At least four congressional committees included the startling accusation in their investigations of possible Russian meddling in the election campaign and Russian ties to Trump and his associates.
It doesn't appear that Trump read the article closely, however, because it does not say Obama personally ordered a tap on his phones during the election, as Trump claimed in his tweet.
"The evidence remains the same", Nunes said Wednesday.
The Republican and Democratic leaders of the Senate Intelligence Committee joined the chorus of lawmakers stating they are not aware of any evidence supporting President Trump's claim that his campaign headquarters was wiretapped during the presidential election.

Dan Patrick and the NRG Stadium Security are also still on the case but no updates have been released. Brady said his jersey went missing after the Patriots' 34-28 win last month over the Atlanta Falcons.
On Wednesday the two heads of the House of Representatives Intelligence Committee also said they had received no information that would back the Trump tweets, and earlier this week top White House aide Kellyanne Conway said she did not know anything to justify it.
Trump has not produced any evidence to support his claim.
Trump explained that his spokesman was simply repeating what he had heard a legal analyst say on Fox News.
Critics of Trump's use of the platform are not alone: 61 percent of voters said in late January they think Trump uses Twitter "too much", up 5 points from another Morning Consult/POLITICO survey conducted in December.
The two cited media reports that said both the Federal Bureau of Investigation and Justice Department were involved, raising questions about the "content and context of Mr. Flynn's discussions with Russian officials". "And we're in the process of putting it together, and I think it's going to be very demonstrative".
During his briefing with reporters, Spicer said that Trump's "wiretapping" accusation did not necessarily refer to wiretapping itself, but meant surveillance more broadly.
While he had offered no evidence, the president can access information on law enforcement and intelligence investigations, and possibly possessed some classified information supporting the claim.
