Yes, if they have support of the President or a veto-proof supermajority in both houses.
> If that's the case, it might be possible to pass such a law when(if) dems take over the House/Senate next year right?
Unlikely, for the reasons stated above, though tying it to something the President isn't willing to veto might work. Or, I guess, if after taking both houses of Congress (and, critically, electing a new Speaker) they also impeach, convict, and remove the Vice President and President, and the Democratic Speaker succeeds to the Presidency, then it would be doable.
Dammit, I had no idea Congress needs 2/3 majority in both houses to override a veto. That seems to make it impossible, even if the Democrats do take control of both Houses.
Or, also within the realm of possibility, Trump flip flops on his positions to side with the Dems, just because he doesn't want to be seen as being out of power.
