♪ ♪ good evening. thank you for joining us. florida's republican governor ron desantis' plan to remap some of the state's congressional districts will increase the number of florida republicans elected to congress for many years to come. the governor says it's fair. his critics say the plan discriminates against people of color, because it will become harder to elect black candidates. >> we want our district to stay the way it is. >> reporter: here in tallahassee, florida, dozens of protestors are gathered on the steps of the state capitol. >> they don't talk right, call

them out. they don't vote right, call them out. >> reporter: they're hear as lawmakers begin a special session to approve a special map proposed by governor ron desantis, which reduces the number of districts in florida with mostly black voters, in what critics say diminishes black representation. >> i'm not only fighting for myself, but i'm fighting for the future of my children, my grandchildren. so that we will still have the right to vote. >> this is an attack on black representation! our concern is that this governor seems to have something against black people. >> reporter: the proposed redistricting in florida drastically alters two districts, held by black democrats, including the fifth district, an area that stretches between jacksonville and tallahassee that consist of predominantly black communities, which the governor called racially gerrymandered to

benefit democrats. >> we are not going to have it divvied up based on the color of skin. that is wrong. >> what governor desantis is demanding is that those voters be spread throughout other congressional districts, and they will be spread in such a way it makes it very difficult to get a democrat or a black representative in particular elected from those districts. >> we're here at this special session. >> reporter: some of his fellow republican party members rallying, supporting him in today's special session. >> in the process, the governor has the ability to veto. that is part of the process. this is a good map. ly be supporting it. i will have no regrets, and i think history will judge me just fine. what is the governor is doing and has done sun precedented. no governor in the state of florida has done what the governor is doing when it comes to drawing maps. >> reporter: senator jones is a democrat, who represents the 35th district. he believes marginalized communities are the most at risk, with the governor's plan.

>> it is important that everyone who is represented in congressional districts, state legislatures or even in municipalities, that they have someone who sits at the table, who represents them. and that has been the norm in this state for quite some time, to ensure that black representation and what's done in congress, but it seems that has gone out the window. because now the governor says that there's no need for that any more. >> reporter: in a press conference this morning, governor desantis added, today's special session would also look into terminating special districts enacted before 1968. >> we are expanding the call of what they are going to be considering this week, and that includes the reedy creek improvement district.p>> report potentially end the special status that allows disney, the parent company of abc, to operate its orlando theme park as an independent government. it's just the latest in the

governor's high profile political battles that have landed him on the national stage. >> to observers in florida and nationwide, the way that governor desantis has governed smacks of an attempt to burnish a resume for a presidential run. the conventional wisdom is he's trying to put as many conservatives on the board as he can in advance of a run to president. we turn now to the crisis in the west. the mighty colorado liver is a lifeline for tens of millions of people, and the economy throughout much of the southwest. but the river is now facing a major test that could impact the lives of millions. abc is in colorado tonight. ♪ ♪ >> reporter: it is the lifeblood of the american west. the colorado river now at a tipping point. >> it's our primary source of income. sit our livelihood. >> reporter: for five

planting drought tolerant grasses for their cows and measuring water use. >> so this is a meadow that you and your family rebuilt. >> rebuilt it about eight years ago. this field produces more yield and uses less water. this is a project we're trying to figure out how to duplicate it. >> reporter: paul now sits on the colorado water conservation board. what has that been like to you to lead ranches into the future with a lot less watter? >> it's an honor and also terrifying. these are tough conversations when people realize that survival will require adaptation. without adaptation, you know, we won't be here for our generation or the generation after us. >> the river is what ties everybody together. without the river, we don't have agriculture, we don't have anything. people better figure out how to keep water in the river.
