There will be a huge effort by the Dems and other deep state within DOJ/FBI to discredit the memo as inaccurate or untrue. POTUS has authority to declassify. For each point that is made to discredit the document, there should be release of corroborating material showing what really happened in the Obama regime (redacting sources & methods that could compromise national security if needed to allow release), and then let the public decide what to believe.
