ROME (AP) -- Rome's embattled mayor is under mounting pressure to resign following a new scandal over his expense accounts.
Rome prosecutors this week opened an investigation into Mayor Ignazio Marino's use of his city hall credit card after questions arose about whether he expensed family dinners, claiming they were official business.
Newspapers have documented a half-dozen dinners where either the alleged guests or the restaurant itself disputed Marino's version of events.
After days of mud-slinging, Marino promised Wednesday to give back 20,000 euros ($22,600), but there were indications that won't be enough given his Democratic Party has essentially yanked its support.
Marino has been increasingly isolated by his own party following a series of scandals and corruption probes.
