If you don’t support and investigation right now, then you don’t support an investigation right now. Losing the “right now” makes the meaning less clear.
I’d be fine with saying they don’t support it right now
But that applies for everything. “Right now” would only be relevant if it is clearly implied that in the future they would support it.
Why would they support an investigation in the future if they don’t support it right now? They cannot even “support it in the future” because most evidence will likely be lost over time. Investigations need to happen as soon as possible.
