The top lawyer for the Trump transition team has ordered the organization's staff to preserve all records and other materials related to the widening investigation by special counsel Robert Mueller into contacts between the Trump campaign and Russian representatives.

The move ordered Thursday by the transition's general counsel cast a wide net on documents tied to the Russia investigation as well as inquiries into the activities of Trump associates. Those associates include former national security adviser Mike Flynn, campaign chairman Paul Manafort, foreign policy aide Carter Page and outside adviser Roger Stone.

The move was confirmed by a transition official who spoke on condition of anonymity to discuss post-election decisions.

The order came the same day that Vice President Mike Pence hired an outside lawyer to represent his legal interests.
