Washington, London- US President Donald Trump has accused former president Barack Obama of wire-tapping his office telephones during last year's election, without offering any evidence or explanation.
Despite the severity of his claim, Mr Trump did not provide any evidence Mr Obama was responsible for surveillance at his property and has not provided any since.
Obama's spokesman, however, described the allegations as "simply false".
The White House on Sunday demanded that Congress investigate whether Obama abused his executive powers, without providing any evidence the former president had done so.
China to increase 2017 military spending by 7 percent
The announcement comes amid USA plans to boost military and security spending by 10 percent. Chinese Premier Li Keqiang will announce China's economic growth target on Sunday.
Mr Obama's spokesman denied the allegations, saying any suggestion he or his staff "ordered surveillance on any U.S. citizen" was false.

Ben Sasse called the US President's surveillance claims serious and said the public deserved more information.
Democrats elect former Obama Labor Secretary Tom Perez as national party chairman
The resistance, of course, is the groundswell of opposition that President Trump, a Republican, has felt since taking office. A dark-horse candidate was Pete Buttigieg , the mayor of South Bend, Ind., who was endorsed by former DNC chair Howard Dean.
"One of the focus points of the House Intelligence Committee's investigation is the us government's response to actions taken by Russian intelligence agents during the presidential campaign. A NEW LOW!" the president continued.
In a series of 6 tweets, including this one, Trump said Obama had his "wires tapped" in Trump Tower, but found nothing.
And in an additional message, he said: "How low has President Obama gone to tapp (sic) my phones during the very sacred election process". And he called Obama a "Bad (or sick) guy". Nothing found. This is McCarthyism! Trump said. "Can that be possible?"
Trump's accusations were possibly brought on by various Conservative talk radio hosts and an unproven Breitbart article that states Obama's White House had authorized secret wiretaps into the phones of Trump's campaign hub in Trump Tower last fall. Rather than Russian Federation, we're talking about, did President Obama do thus and so?
Snapchat Is Now Worth Around $30 Billion After Successful NYSE Debut
Lightspeed was the first to back Snapchat and now owns a stake in the company worth almost $2 billion. "Everyone is super happy". And that decision just paid off big: His stake in Snap is worth $68 million based on the opening price.
Obama's office did not immediately respond to a request for comment from Reuters. It would be a highly unusual breach of the Justice Department's traditional independence on law enforcement matters for the White House to order it to turn over such an investigative document.
