Joyce's travails deepened when Broad told the ABC on Thursday he had the endorsement of his local branch in the Mallee to call on Joyce to resign the leadership of the National party next Monday.
Joyce had spent the past week on "holiday" in Armidale, though he made a number of media appearances, including a candid interview with his partner and former media advisor, Vikki Campion.
With Malcolm Turnbull in the United States and Mr Joyce on leave, Senator Cormann said any allegation of sexual harassment is very serious.
"All complaints are taken seriously and treated with the strict confidentiality and given due process", National Party federal director Ben Hindmarsh said in a statement. "I don't believe any of them have been sustained", he said.
"As it stands today Barnaby has my full support", he said. "At this point in time, it is not fit for Barnaby to. step up as acting PM".
Joyce and Ms Campion are expecting their first child together in April.
But the spokesman repeatedly refused to provide answers to questions about vehicle expenses during the period.

Slovakia scored a second-period, power-play goal by Peter Ceresnak through traffic that Zapolski had little chance of stopping. Garrett Roe and Donato each added a goal for the U.S.in the third period to close out the game's scoring.
"This current cacophony of issues has to be put aside, and I think it's my responsibility to do my bit to make sure that happens", Mr. Joyce said at the news conference.
Turnbull went so far as to announce a revision in the ministerial code of conduct to prohibit such breaches in the future.
It is understood the agreement sets out priority policy areas, proposed major projects of interest to regional and rural areas, which portfolios the Nationals want on the frontbench and that the Nationals leader will be deputy prime minister.
Joyce had only been back in parliament less than a month after falling victim to a citizenship crisis that has dogged Turnbull's government.
"Mr Joyce's actions have caused pain for his family but it is the ongoing damage he is causing The Nationals organisation that is of greatest concern to me as WA Leader", Ms Davies said.
Fellow NSW MP and Veterans Affairs Minister Michael McCormack, who recently gave an interview in which he dodged multiple questions about his support for Mr Joyce, is also considered a contender. Several of his party members have called for Mr Joyce's resignation.
It appears to be a sexual harassment allegation, made to the Nationals from a Western Australian woman, that led to Mr Joyce deciding to step down from the leadership after being under pressure for weeks.
