Rudy Giuliani claims he's broke, but his soon-to-be-ex-wife argues that he's hiding his wealth and squandering his money working for President Donald Trump.

The former New York City mayor and his estranged wife Judith Giuliani are locked in a bitter divorce battle, and the ex-couple appeared Thursday in court to argue over their joint bank account, reported Bloomberg.

The 75-year-old Giuliani told the court he was forced to borrow $100,000 from Trump lawyer Marc Mukasey, his former law partner, after spending $800,000 so far this year on "marital expenses" related to the couple's lavish lifestyle.

In a column for the New York Times, Nobel Prize-winning economist Paul Krugman exposed Donald Trump's massive tax cut for wealthy Americans and what it also contains: a literal hand-out of billions of dollars to foreign investors.

Sarcastically calling it "Trump’s Secret Foreign Aid Program," the columnist said the president has successfully pulled off a massive "giveaway" to the rich -- including wealthy foreigners.

"Donald Trump often complains that the media don’t give him credit for his achievements. And I can think of at least one case where that’s true. As far I can tell, almost nobody is reporting that he has presided over a huge — but hidden — increase in foreign aid, the money America gives to foreigners. In fact, the hidden Trump program, currently running at around $40 billion a year, is probably the biggest giveaway to other nations since the Marshall Plan," Krugman wrote, before pithily adding, "Unfortunately, the aid isn’t going either to poor countries or to America’s allies. Instead, it’s going to wealthy foreign investors."

Treasury Secretary Steve Mnuchin is defying a congressional request to hand over President Donald Trump's tax returns on the ground that asking for the president's taxes is supposedly an "unprecedented" invasion of privacy.

The Washington Post is reporting, however, that Congressional Democrats this week unearthed a new set of documents dating from 1973 that show requesting Trump's taxes is entirely within the bounds of political norms.
