Flávio Bolsonaro has arrived in the United States after Brazil cancelled his passports, sources told the BBC, leaving questions over his movements while under investigation for alleged money laundering.
The defeated presidential candidate has not been charged and denies the allegations.

Sources told BBC Brasil and BBC Mundo that the 45-year-old senator met his younger brother Eduardo in Florida.
His route, travelling companions and whether he intends to settle in the US remain unclear.
Neither brother could be reached directly for comment.

Brazil’s Supreme Court ordered Bolsonaro on Monday to surrender his passports within 24 hours; they were cancelled on Tuesday after he missed the deadline.
He had said he would remain in Brazil to lead opposition to President Luiz Inácio Lula da Silva.
His lawyers subsequently told BBC Brasil they were “completely in the dark” about his whereabouts.
His last public statement was a social media video on Monday afternoon, local time.

A senior US official confirmed hours before the reported arrival that the State Department would issue visas to Bolsonaro and his family and admit them.
Brazilian federal officers checked border crossings for possible travel to Argentina, a police source said, but Argentine authorities reported no record of his entry.
Eduardo lives in Texas but voted and attended a streamed election-viewing event in Miami on Sunday.

The investigations extend beyond Bolsonaro’s movements.
He was already being investigated over alleged corruption in financing a film about his father, former president Jair Bolsonaro, who was convicted of plotting a coup and is under house arrest.

A separate inquiry concerns alleged links to a lawyer accused of laundering more than $1bn through fraud.
Police said earlier this month that Bolsonaro had access to accounts belonging to the lawyer’s company.
He denied doing business with the lawyer and called the passport confiscation intimidation.
On Tuesday, the Supreme Court also ordered police to examine alleged foreign funding of his campaign.

Sunday’s run-off gave Lula a fourth term, with 51.79% against Bolsonaro’s 48.21%, a gap of 4.4 million votes.
Polls had narrowly favoured Bolsonaro, whose first-round victory on 4 October led analysts to expect him to win.
Lula overcame an early counting deficit to become the first presidential candidate to reverse a first-round defeat in the run-off.

Bolsonaro has not conceded and wants the election annulled, arguing that a court-ordered two-hour voting extension disadvantaged him and calling it a “dirty trick”.
Both parties had requested the extension.
His Liberal Party accepted the result, while saying the extension “merits investigation”.
