Mueller defies Trump warning and expands Russia probe to include family’s business dealings: report

President Donald Trump on Wednesday said that it would be a "red line" if special counsel Robert Mueller began investigating his family's business dealings -- and now a new report from Bloomberg claims Mueller is about to do just that.

One source tells Bloomberg that Mueller's team is "examining a broad range of transactions involving Trump’s businesses as well as those of his associates."

Among other things, the source claimed that "FBI investigators and others are looking at Russian purchases of apartments in Trump buildings, Trump’s involvement in a controversial SoHo development with Russian associates, the 2013 Miss Universe pageant in Moscow and Trump’s sale of a Florida mansion to a Russian oligarch in 2008."

The source claims that Mueller's investigation into Trump's business dealings is picking up from an investigation into a massive money-laundering scheme that was investigated by former Manhattan U.S. Attorney Preet Bharara until he was fired by Trump earlier this year.

The Trump SoHo development has been the object of intrigue for several years now, and one lawsuit brought against the property claimed that Bayrock Group -- the firm that underpinned the financing of the project -- was supported by figures in Russian organized crime.

The 2013 Miss Universe pageant, meanwhile, is the event that connects Trump with the Agalarovs, the Russian family that offered to help Donald Trump Jr. to obtain damaging information on Democratic presidential nominee Hillary Clinton in 2016.
