The US Department of Justice will investigate whether FBI agents spied on President Donald Trump’s 2016 election campaign for “inappropriate purposes”.
In a tweet, Mr Trump said he wanted to know whether his predecessor’s administration ordered such a move.
The call comes after US media reports suggesting the FBI had an informant meeting campaign aides.
US Deputy Attorney-General Rod Rosenstein said action would be taken if any infiltration was found.
“If anyone did infiltrate or surveil participants in a presidential campaign for inappropriate purposes, we need to know about it and take appropriate action,” Mr Rosenstein said in a statement.
