U.S. Attorney General Eric Holder.

The U.S. Justice Department plans to bring civil mortgage fraud cases against several financial institutions early in 2014 using as a template the case that ended last month in JPMorgan Chase's $13 billion settlement, U.S. Attorney General Eric Holder said on Wednesday.

In an interview with Reuters, Holder would not say which firms or how many could face suits but said the Justice Department was in contact with them about the cases and it was hard to say whether the talks would lead to settlements.
