Green Party presidential candidate Jill Stein was heckled and called a 'common criminal' during a news conference outside Trump Tower on Monday as she continues the recount effort in Pennsylvania, Michigan and Wisconsin.

Stein is seeking an emergency federal court order for a recount in Pennsylvania after dropping a state court case due to the required $1million bond.

In Michigan, a hand recount began on the orders of a federal judge, while recount results in Wisconsin, which started on Thursday, showed little change from those reported on election night.

Stein, who received about 1 per cent of the vote in all three states, says her intent is to verify the accuracy of the vote. She has suggested, with no evidence, that votes cast were susceptible to computer hacking.

'Let every vote count. That's what makes America great,' Stein said Monday outside Trump Tower in New York, where she was repeatedly interrupted by shouts of protest.

In Pennsylvania, the Green Party filed a federal lawsuit on Monday seeking a statewide recount — a move that came after the party on Saturday dropped a case set to be argued Monday in state courts.

An updated count Friday by state election officials showed Trump's lead shrinking to 49,000 from 71,000 over Clinton, out of 6 million votes cast, as more counties finish counting overseas ballots and settled provisional ballot challenges.

That is still shy of Pennsylvania's 0.5 per cent trigger for an automatic statewide recount.

Final counts are outstanding in some counties, but there are not enough uncounted votes to change the outcome, officials say.

In Michigan, a federal judge in Detroit ordered a statewide hand recount of roughly 4.8 million ballots on late Sunday night.

Republicans appealed that ruling Monday. Trump won the state by about 10,700 votes, or two-tenths of a percentage point, over Clinton.

Stein argued that a law requiring a break of at least two business days after the Board of Canvassers' final action on a recount request is unconstitutional.

Judge Mark Goldsmith found that Stein had 'shown the likelihood of irreparable harm' if the count was delayed even by two days and rejected the state's arguments about the cost to taxpayers.

Republican Attorney General Bill Schuette, the Trump campaign and super PACs have filed separate lawsuits asking state courts to prevent the recount, arguing that Stein, as the fourth-place finisher, is not 'aggrieved' because she has no chance of winning in a recount. A hearing is scheduled Tuesday on those actions.

The recount began in Wisconsin on Thursday, continuing over the weekend, with little change so far in the unofficial results as reported on election night.

Six counties completed their work as of Monday morning, with the margin between Trump and Clinton unchanged. Both candidates lost 20 votes.

A federal lawsuit was filed late last week by a Trump voter and two super PACs seeking to stop the recount, but a judge rejected the request while the lawsuit is pending and scheduled a hearing for Friday.

State and local election officials have all said they don't expect Clinton to surpass Trump in Wisconsin, where he won by about 22,000 votes.

The Wisconsin Elections Commission said no significant issues have been reported after four full days of recounting and any changes between canvass results and recount totals have been due to human error.

A partial recount is also underway in Nevada at the request of Independent Roque De La Fuente, who paid $14,000 to provide a 'counterbalance' to Stein's efforts

A partial recount is also underway in Nevada at the request of Independent Roque De La Fuente, who finished last with a fraction of 1 per cent of the vote.

He paid about $14,000 for the recount to provide what he called a counterbalance to the recounts sought by Stein.

Most of the 92 precincts being re-counted are in the Las Vegas area, with eight of the precincts in four other counties.

If the sample shows a discrepancy of at least 1 per cent for De La Fuente or Clinton, a full recount will be launched in all 17 Nevada counties.

Clinton defeated Trump in Nevada by 27,202 votes, out of 1.1 million votes cast.

Nevada Secretary of State spokeswoman Gail Anderson said the recount will be finished by the end of this week.
