The secret part of the list, according to the US, is based on intelligence received.
While at a hearing in the US Senate Banking Committee, Finance Minister Stephen Mnuchin said that, based on the list, sanctions would be introduced in the “near future.”
At the same time, the senators expressed impatience, asking Mnuchin why the Kremlin list was left without comment from US President Donald Trump. Mnuchin evasively replied that "the administration is doing everything possible to put the sanctions in force."
Sanctions are likely to work within the next month.
This once again confirms the previously suggested assumption that the sanctions were preparing for the start of the presidential campaign in Russia, which is a direct interference with the Russian elections.
