Trump positions anti-China lawmakers for key roles
Two Florida lawmakers known for their tough stances towards China are in the running for senior foreign relations jobs in the administration of President-elect Donald Trump, US media reports say.
Senator Marco Rubio, who challenged Trump for the 2016 presidential nomination, is in talks to be his future secretary of state, two sources told the BBC's US partner, CBS News. But his appointment has not yet been agreed.
And Michael Waltz, a congressman and military veteran, could play his own significant role in Trump's new government. He is favourite for the national security adviser, two sources familiar told CBS.
Rubio and Waltz's offices have not responded to the BBC's request for comment.
Trump's administration is starting to take shape after his win in last week's presidential election.
His Republican Party is closing in on full control of Congress. They have won back control of the Senate, the upper chamber, and they are inching towards a majority in the House, the lower chamber, as vote-counting continues.
Some of the appointments - including secretary of state - will require senators' approval, although Trump has demanded that the next Senate leader let him bypass this. He can give out other jobs - like national security adviser - directly.
The reported roles for Rubio and Waltz come after Trump made Susie Wiles his chief of staff, named former immigration official Tom Homan as his "border tsar" and nominated New York Congresswoman Elise Stefanik as his future ambassador to the United Nations.
A president-elect has responsibility for about 4,000 political appointments. During his first presidency, it took Trump months to assemble his cabinet.
Rubio - the foreign policy hawk
It is not yet certain that Rubio, 53, will be nominated to serve as secretary of state - a role that functions as America's top diplomat - but the Florida Republican's career has set him up to take the role.
Several US media outlets have reported that Rubio is in talks with the Trump transition team over the senior position, but it has not been finalised. It appears the president-elect could still change his mind.
Rubio serves as the vice-chairman of the Senate Intelligence Committee and sits on the Foreign Relations Committee.
He is considered a foreign policy "hawk" - meaning someone who takes hard-line positions - towards Iran as well as China.
While supportive of Ukraine, he previously said the country's war with Russia needed to "be brought to a conclusion”.
Rubio and Trump were opponents in the race for the Republican presidential nomination in 2016 and the two developed a bitter rivalry.
They clashed on a variety of issues - particularly immigration - and the conflict led to various insults. Trump referred to the senator as “little Marco” and Rubio mocked Trump's "small hands".
But Rubio went on to endorse his rival and campaigned for him ahead of the 2024 election. He was also in the frame to be Trump's running mate - a role that ultimately went to JD Vance, who takes a similar view towards China.
Rubio, the son of working-class Cuban immigrants, was first elected to the Senate in 2010.
