Washington, Dec. 11 : Senate Republicans are considering asking former US President Bill Clinton to testify at his wife, Hillary's confirmation hearing.

The focus of the testimony could be about potential conflicts of interest involving his worldwide charitable enterprises, reports Politico.

"There are concerns about his international work across the board. Seeking donations from foreign governments is definitely concerning. ... It has been discussed, and it will be discussed," a Republican aide, speaking on the condition of anonymity, told Politico.

While spouses frequently attend nominees' confirmation hearings, they are usually there for moral support and window dressing - a sympathetic face in the row of seats behind the witness table.

Indeed, it's unusual to have anyone aside from the nominee testify at a confirmation hearing.

One of the Republicans most concerned about Bill Clinton's role is Senator David Vitter, a Republican from Louisanna.

Democratic aides say the former president has already resolved any conflict-of-interest issues by agreeing to forgo fundraising from foreign governments.

If Republican senators have questions about the arrangement, the Democratic aides say, those questions could be "handled in private" - before the confirmation hearing begins - or during the questioning of Hillary Clinton herself. (ANI)
