U.S. Chief Justice John Roberts will be a central figure in the ongoing drama of the Donald Trump presidency in the coming months. He is due to preside over a Senate impeachment trial, while the Supreme Court he leads will rule on a titanic clash over the president's attempts to keep his financial records secret.
The expected impeachment trial will focus on accusations that Trump abused his power by asking Ukraine to investigate former Democratic Vice President Joe Biden. The Democratic-led House of Representatives approved two articles of impeachment on Dec. 18, paving the way for the trial in the Republican-led Senate.
The normally reserved and mild-mannered Roberts, 64, will have the largely symbolic role of presiding officer, with senators casting the crucial votes.
