In the NYT on the 1st, in the story “Baltimore Police Complete Initial Inquiry Into Death of Prisoner”, this quote from Baltimore state’s attorney Marilyn Mosby:
“While we have and will continue to leverage the information received by the department, we are not relying solely on their findings but rather on the facts that we have gathered and verified.”
This would be labeled as a straightforward grammatical error by many commenters: a failure of parallelism in coordination, the result of failing to include all necessary words (possibly as a consequence of failing to attend to the syntax of sentences as they are being produced):
NOT we have and will continue to leverage …
BUT we have leveraged and will continue to leverage …
The have of the perfect governs a PSP complement, but there is no PSP VP in the example, only a BSE VP (continue to leverage …) governed by the modal will, an infinitival VP (to leverage …) governed by continue, and a BSE VP (leverage …) governed by infinitival to. The second part of the coordination is fine, but the first part fails the government requirement on the perfect. Put another way, the government requirement in the first conjunct is disregarded, and we see government determined by the nearest governor to the affected VP. In short, government by the nearest (GbN).
