I'll listen to what the major research organizations recommend, but there are many medical experts that are questioning this decision. It could be because of supply issues or it could be politically motivated. The article linked below does mention the change in policy originally came from HHS and not directly from the CDC. It also mentions that a testing supply shortage may be a factor as well (which shouldn't be happening at this point).
Just another example of how this administration has cast doubt on the competency of every aspect of our government and why it is important to not do that. The CDC just gave an order and instead of doing what they can to follow it everyone is wondering where in the hell the decision to make such a major and drastic change in policy came from.
Dr. Robert R. Redfield, director of the Centers for Disease Control and Prevention, offered clarification regarding the new COVID-19 testing guidelines released by the agency Wednesday that raised questions in the heath care community.

*Note: The article also mentions that HHS is going to hold a briefing so hopefully some evidence to go with the decision will be presented there.
