Can Trump fire Federal Reserve chair Jerome Powell?

The US president and the man he appointed to head the central bank are at loggerheads over interest rates

After years of heated attacks on the Federal Reserve chair, Jerome Powell, the Trump administration has begun suggesting recent costly renovations at the central bank's Washington DC buildings could justify firing Powell.

Donald Trump's antipathy for Powell stems mainly from the central bank boss's refusal to lower interest rates - something the president has repeatedly called for.
