U.S. Attorney Paul J. Fishman announced the pair was charged Monday in an alleged conspiracy to defraud lenders and illegally obtain mortgages and other loans, as well as allegedly hiding assets and income during a bankruptcy case.
"The indictment returned today alleges the Giudices lied to the bankruptcy court, to the IRS and to a number of banks," Fishman said in a statement. "Everyone has an obligation to tell the truth when dealing with the courts, paying their taxes and applying for loans or mortgages. That's reality."
"Today is a most difficult day for our family," Teresa said in a statement via Twitter Monday.
"I support Joe and, as a wonderful husband and father, I know he wants only the best for our lovely daughters and me," she tweeted. "I am committed to my family and intend to maintain our lives in the best way possible, which includes continuing my career. As a result, I am hopeful that we will resolve this matter with the government as quickly as possible."
A source close to the reality star told E! News Monday: "She's shockingly, shockingly calm about this. She's been at the family's shore house with her daughters and now she's driving back up for her court appearance tomorrow morning."
The insider said Teresa and Joe will have their own lawyers but emphasized the couple "have been tighter than ever.
"They've been together constantly and, sadly, their relationship seemed very strong before this news hit," the source said.
