Lighthizer had also expressed interest in serving as Treasury secretary, but that position will most likely be offered to a financier, with contenders including the hedge fund managers Scott Bessent and John Paulson.
The possibility of an arch protectionist being reappointed to the pivotal trade role is likely to raise concerns in Beijing, as well as among US trading allies, given how influential Lighthizer was during Trump’s trade wars during his first term. Trump has vowed to impose high tariffs on all imports into the US, particularly Chinese goods.
Trump had considered Lighthizer for commerce secretary but the people familiar with the personnel discussions said the president-elect was most likely to offer that job to Linda McMahon, the billionaire co-chair of Trump’s presidential transition team.
