WASHINGTON: US Vice President Kamala Harris said she was ready to serve as leader, in a Wall Street Journal interview published on Monday, as voter concerns mount about President Joe Biden`s age in an election year.

The 59-year-old Harris has faced growing scrutiny about her own abilities as the first in line to the presidency should Democrat Biden, 81, be incapacitated or stand down.

`I am ready to serve. There`s no question about that, Harris told the newspaper when asked whether voters` concerns about Biden`s age meant she must convince them of her credentials.

Everyone who sees her on the job `walks away fully aware of my capacity to lead`, said Harris, the first Black, South Asian and female vice president in US history.

The interview was carried out two days before a stinging special counsel report last week portrayed Biden as elderly and forgetful.

Special counsel Robert Hur`s probe into Biden`s handling of classified documents said the president should not face charges, but damningly said he would come across to a jury as a `well-meaning, elderly man with a poor memory`.-AFP
