Bill Clinton to stump for Hillary in New Hampshire on Monday: reports

Former President Bill Clinton hits the campaign trail Monday for his wife Hillary -- his first appearance on the stump for the former first lady's White House bid.

US media reported that Bill Clinton will hold a rally at a community college in the city of Nashua and another event later Monday in the city of Exeter.

The former president's visit to New Hampshire in support of his wife comes after Republican presidential frontrunner Donald Trump has sharpened his attacks on both Clintons.

Trump, who leads the Republican field by a large margin in nationwide polls, has turned recently from attacking his fellow Republican candidates to stepping up his criticism of the Clintons.

Last month, he blasted Bill Clinton's "terrible record" with women -- an apparent illusion to rumored past marital infidelities, including while in the White House.

"If Hillary thinks she can unleash her husband, with his terrible record of women abuse, while playing the women's card on me, she's wrong!" Trump recently tweeted.

The billionaire businessman has called Bill Clinton's past reported affairs "fair game" in the 2016 campaign.

Accusations of sexual impropriety dating back to his time as governor of Arkansas have dogged Clinton for years.

Republicans in Congress tried but failed in 1998 to remove him from office for alleged perjury and obstruction during an investigation into an alleged White House affair.

New Hampshire is host to the nation's first presidential primary on February 9.

Voters in the heartland state of Iowa, using the caucus method, will register their presidential preference on February 1.
