House fails to override Trump veto on national emergency

Speaker Nancy Pelosi issued the following statement after the vote:

"Both chambers of Congress — a Democratic House and a Republican Senate — resoundingly rejected the President's sham emergency declaration by passing H.J.Res.46. This will provide significant evidence for the courts as they review lawsuits. The President's lawless emergency declaration clearly violates the Congress' exclusive power of the purse, and the Congress will work through the appropriations and defense authorization processes to terminate this dangerous action and restore our constitutional system of balance of powers."

What to watch: The Pentagon Monday night authorized up to $1 billion for building the wall, but that authorization was rejected on Tuesday by House Armed Services chairman Adam Smith.

• Per Politico, it's unclear to what extent Smith's rejection can affect the $1 billion authorization, since the Pentagon was acting on orders from the president.

Earlier this month, the Defense Department provided Congress with a plan to collect $12.9 billion for the border wall from various military construction projects across the country.
