More than a week after United States president Donald Trump tweeted his extraordinary, unsubstantiated wiretapping claims against Barack Obama, he is yet to provide any evidence.
Mr Trump tweeted that President Obama had Trump Tower wiretapped during the US election campaign.
Now, both the Republican and Democratic leaders on the House of Representatives Intelligence Committee say there is no evidence of such wiretapping.
Democratic Congressman Adam Schiff says he thinks the White House has been trying to downplay the fact the President said something not true.
