Hillary Clinton to announce White House run Sunday; her fame both bonus and burden

Controversy and criticism

Clinton has been a target for Republican criticism since Bill Clinton`s first presidential campaign. He promised voters then that they would get "two for one" by putting them both in the White House, but quickly dropped that claim when it proved unpopular.

Hillary Clinton`s biggest initiative while her husband was president, national healthcare reform, fell apart without coming to a vote in Congress.

She became a figure of public fascination, and admiration in some quarters, for standing by her husband when allegations of his sexual infidelities first surfaced during his 1992 presidential campaign, and again in 1998 when his affair with White House intern Monica Lewinsky surfaced.

Both the Clintons have been investigated repeatedly by Republican lawmakers and the then United States Office of the Independent Counsel.

As Hillary Clinton prepared to start her campaign, she faced criticism from Republicans for using only a personal email account while secretary of state, and for the Clinton Foundation`s reliance on donations and payments from foreign governments for its philanthropy work abroad, even as she served as the country`s top diplomat.

Clinton has said she should have used a government email account as secretary of state while insisting that she had violated no rules.

During the campaign, Clinton will be expected to say whether she will more closely align with the centrist economic policies of her husband`s administration or the populist policies championed by the progressive wing of her party.

Some Democrats have urged Senator Elizabeth Warren of Massachusetts, a leader of the party`s liberal wing and a critic of Wall Street and big banks, to challenge her, but Warren has declined.
