FBI wiretapped Trump campaign chief Paul Manafort - reports
Donald Trump's campaign chairman, Paul Manafort, was wiretapped by the FBI due to concerns about his links with Moscow, US media reports say.
The reported surveillance, granted under a court warrant, occurred both before and after the 2016 election.
Investigators wanted to know if he had sought Russian help with the campaign.
It is not known if the wiretap, which began in 2014, included conversations with President Trump. Mr Manafort is said to be facing an indictment.
The former political consultant, who had worked for Ukraine's former ruling party, was chairman of the Trump campaign from June to August 2016. He has not commented on the reports.
FBI special counsel Robert Mueller is leading an investigation into alleged attempts by Russia to influence the 2016 election.
However, the Foreign Intelligence Surveillance Act (FISA) warrants were granted before his investigation started, and were first authorised as part of an investigation into Washington consulting firms working for Ukraine, CNN reported.
After the 2014 warrant ended, it was renewed again until earlier this year, in order to allow the FBI to investigate ties between Trump campaign associates and suspected Russian operatives.
Hurricane Maria regains strength after battering Dominica
The latest major Atlantic hurricane of the season, Maria, has powered back to category five strength after pounding the Caribbean island of Dominica.
It weakened to a four after wreaking "widespread damage" on the island but is now packing maximum sustained winds of 260km/h (160mph) again.
The storm is moving roughly along the same track as Irma, this season's other category five hurricane.
Maria is now heading towards the Virgin Islands and Puerto Rico.
The governor of Puerto Rico, a US territory, has told the island's 3.5 million people to seek shelter.
Trump: US would destroy North Korea if forced to defend itself
US President Donald Trump has told the UN General Assembly that America would destroy North Korea if forced to defend itself or its allies.
In his debut speech, he mocked North Korea's leader, Kim Jong-un, saying: "Rocket man is on a suicide mission."
North Korea has tested nuclear bombs and missiles in defiance of the UN.
The American leader also attacked Iran, saying it was a "corrupt dictatorship" which was intent on destabilising the Middle East.
He called on the government in Tehran to cease supporting terrorism and again criticised the Obama-era deal over Iran's nuclear programme, which he called an embarrassment.
