Even the New York Times admitted that Obama holdovers had committed crimes, probably including espionage, sedition, sabotage, obstruction of justice, and/or subornation of perjury in the transitional period. From the NYT March 1, 2017:
As Inauguration Day approached, Obama White House officials grew convinced that the intelligence was damning and that they needed to ensure that as many people as possible inside government could see it, even if people without security clearances could not. Some officials began asking specific questions at intelligence briefings, knowing the answers would be archived and could be easily unearthed by investigators — including the Senate Intelligence Committee, which in early January announced an inquiry into Russian efforts to influence the election.
At intelligence agencies, there was a push to process as much raw intelligence as possible into analyses, and to keep the reports at a relatively low classification level to ensure as wide a readership as possible across the government — and, in some cases, among European allies. This allowed the upload of as much intelligence as possible to Intellipedia, a secret wiki used by American analysts to share information.
The opposite happened with the most sensitive intelligence, including the names of sources and the identities of foreigners who were regularly monitored. Officials tightened the already small number of people who could access that information. They knew the information could not be kept from the new president or his top advisers, but wanted to narrow the number of people who might see the information, officials said.
More than a half-dozen current and former officials described various aspects of the effort to preserve and distribute the intelligence, and some said they were speaking to draw attention to the material and ensure proper investigation by Congress. All spoke on the condition of anonymity because they were discussing classified information, nearly all of which remains secret, making an independent public assessment of the competing Obama and Trump administration claims impossible.
Thus, it is only natural that they continue sabotaging President Trump and the new administration. Sessions’ recusal and the Mueller investigation allowed the Democrats to effectively control DOJ for a year and a half after Trump inauguration.
