Later in the segment:
MSNBC host Lawrence O'Donnell issued an on-air clarification Tuesday after making shocking claims about President Donald Trump's ties to Russian oligarchs that had not been vetted by NBC News.
In response to a Democrat-controlled House committee subpoena, Deutsche Bank revealed Tuesday that it was in possession of tax returns "related to" Trump or his immediate family. While the partially redacted filings did not specify whose tax returns the bank possessed, O'Donnell opened The Last Word by claiming they were President Trump's, based on "what one source close to Deutsche Bank has revealed to me."
A source close to Deutsche Bank says Trump’s tax returns show he pays very little income tax and, more importantly, that his loans have Russian co-signers.— Lawrence O'Donnell (@Lawrence) August 28, 2019
If true, that explains every kind word Trump has ever said about Russia and Putin. @TheLastWord 10pm
"The source says that Deutsche Bank is in possession of loan documents that show Donald Trump has obtained loans with co-signers, and that he would not have been able to obtain those loans without co-signers," O'Donnell said. "The source close to Deutsche Bank says that the co-signers of Donald Trump's Deutsche Bank loans are Russian billionaires close to Vladimir Putin."
"Now, I want to stress, that's a single source. This has not been confirmed by NBC News, I have not seen any documentation from Deutsche Bank that supports this and verifies this," he said. "This is just a single source who has revealed that to me."
So, O'Donnell nor his source have seen the relevant documents that this bombshell was based on. Disgraceful.
Deutsche Bank is declining to comment on Lawrence O’Donnell’s reporting that Russian oligarch’s co-signed Trump’s loans. The information came from a single source who has not seen the bank records. NBC has not seen those records and has not yet been able to verify the reporting.— Michael Del Moro (@MikeDelMoro) August 28, 2019
