The NYT has a wrap on the Trump White House's scramble to respond to the president accusing former President Obama — over Twitter, nonetheless, of wiretapping him during the campaign. Paragraphs 9 and 10 are rather interesting:
Why it matters: Pay attention to how the Obama folks worded their denial of ordering a tap on Trump. They explicitly said presidents can't order — and don't have access to — such actions during active investigations. If there is such an active investigation, the White House would be entering unusual territory seeking access to it.
