Based on the ACLU article linked to in this article, this article is wrong.

Cohen has claimed that because he is an attorney — for Trump and others — some of the seized files may be entirely off-limits to the government because they are protected by the attorney–client privilege. President Trump’s lawyers have made similar arguments. Both have asked the court to allow their legal teams to have the first cut at the seized files in order to review them for privilege, and then to produce the remainder to the government or a special master. The government has countered that the court should allow a so-called “taint team,” made up of prosecutors who are not assigned to the case and who are technically walled off from those working on the case, to do the sorting. The court is now considering the parties’ arguments and is expected to rule quickly.
