Here ya go - From the article, which can be checked via the 12 Amendment: "The deadlines for filing a recount request in both states arrive next week. But the December 13 deadline for finishing the recounts is set by federal law and would apply to both Michigan and Pennsylvania as well.
If none of the states are able to certify their vote counts in time for the deadline, which comes six days before the December 19 Electoral College vote, Trump could lose a total of 46 electoral votes, leaving him with 260 — 10 short of the required 270.
Electors from those states could meet on December 19 regardless, to cast their votes. But in that case, the legitimacy of those votes would likely face legal challenges, before Congress officially counts and finalizes the votes on January 6.
Clinton remains at 232, so if the three states all miss the recount deadline, no candidate would possess the required majority and the election would be thrown to the House of Representatives to decide, with each state delegation receiving one collective vote. The last time that happened was 1824, when the House picked John Quincy Adams over Andrew Jackson, even though Jackson won the popular vote."
