Beginning on February 26th, the House passed a measure to overturn Trump’s Emergency Declaration, voting 245-182, just 11 days after the declaration was made [1].
Eventually, the measure was moved to the Senate, where on March 14th, 12 Republicans voted for the measure to be moved forward, with a vote of 59-41, passing the Senate but not within a veto-proof majority [2].
From there, Trump announced his intentions of Vetoing the measure, and did so the following day [3].
Now, Nancy Pelosi, Speaker of the House, is expected to challenge his Veto in the House, publicly stating that she’d do so by having an override vote take place on March 26th [4].
In this instance, Nancy Pelosi’s vote on March 26th is unlikely to pass, as a Supermajority of 2/3 is needed to override a Presidential Veto, meaning 67 members of the Senate or 290 members of the House, which neither Congressional House met during the vote.
The Emergency on the Southern Border, however, isn’t an emergency at all [5], and will inevitably be forgotten after Trump leaves office.
There is a long process needed to get the land on the southern border, requiring Eminent Domain utilization by the Federal Government, in which the government can seize private land for their own use. This was done during the W. Bush and Obama Presidencies to allow for the Secure Fence Act, against the wishes of many who owned the land, which put the current Border Fence we have lining the most accessible portions of the United State’s Southern Border that is there today [6].
