Hello and welcome to the US politics live blog.

President Donald Trump’s choice to lead the Federal Reserve will commit to protecting central bank independence on interest rates at a crucial confirmation hearing later today.

“I am committed to ensuring that the conduct of monetary policy remains strictly independent,” Kevin Warsh is to say in an opening statement to the Senate Banking Committee. He is also expected to express commitment to fighting inflation, according to remarks seen by the AFP news agency.

The hearing, scheduled for 10am ET, will be closely watched as it marks a key hurdle Warsh must overcome in order to succeed Fed chair Jerome Powell when his term ends on 15 May.

But the session will be tense, with all 11 Democrats on the Banking Committee last week urging for a delay in the nomination’s proceedings until separate investigations into Powell and Fed governor Lisa Cook are closed.

Republican senator Thom Tillis, who sits on the panel led by his party, has also vowed to block all Fed nominees – including Warsh – until the Justice Department probe involving Powell is resolved. With 13 Republican members on the committee, Tillis’ vote against Warsh’s confirmation could be enough to set up an impasse.

Warsh is due to face questioning from lawmakers on issues ranging from his wealth to past connections with the late sex offender Jeffrey Epstein, alongside his views on economic issues.
