Trump's excuse for not signing Russia-sanctions bill involves time-travel.

Trump got the bill on July 28th:

In fact, according to the records at Congress.gov, the bill was formally sent to the White House. Here is a screenshot of the official record, which confirms the bill was “presented to the president” on July 28, 2017.

The White House said on Friday night that President Trump would sign legislation imposing sweeping sanctions against Russia and curtailing his own power to lift them by himself, bowing to the near-universal bipartisan will of Congress at the risk of escalating tension with Moscow.

“President Donald J. Trump read early drafts of the bill and negotiated regarding critical elements of it,” Sarah Huckabee Sanders, the White House press secretary, said in a written statement released late in the evening. “He has now reviewed the final version and, based on its responsiveness to his negotiations, approves the bill and intends to sign it.”



No, wait. Scratch that. He has read the bill and intends to sign it but cannot sign it because he hasn't read it yet.
