Before Nevada lawmakers adjourn at or before midnight, they must give final approval to a two-year state budget expected to total about $25.7 billion. They're also expected to consider sprawling changes to the state's criminal justice laws and a revamp of the way Nevada allocates education funding.

The tasks cap a session in which the Democrat-controlled Legislature, emboldened by an expanded majority and the state's first Democratic governor in two decades, expanded voting rights, toughened gun laws and allowed state workers to collectively bargain.

The 2019 Legislature was also the nation's first with an overall female majority who ushered in a bill to rewrite abortion rules.

The biennial session ends Monday at midnight and lawmakers are expected to work up to the stroke of midnight as they work through dozens of bills.

Lawmakers have passed more than 400 bills and will whip through dozens more before they adjourn at midnight Monday. Some bills brought forward but did not pass include two bills to ban the death penalty and a measure that would have banned Nevada's legal brothels.

Here's a look at where some key bills lawmakers took on this year:
  
ABORTION
  
While conservative states this year have been passing more restrictive abortion laws, Nevada moved in the opposite direction. Democratic Gov. Steve Sisolak signed into law a measure that repeals a requirement that a woman be asked about her marital status before an abortion and a requirement that physicians tell a woman about the "emotional implications" of the procedure.
  
___
  
COLLECTIVE BARGAINING
  
A bill to allow state workers to collectively bargain for better wages and working conditions is headed to Sisolak's desk. The bill, which Sisolak called for in his State of the State address, would cover workers like prison guards, janitors and secretaries. It would not cover teachers and workers would not be permitted to strike.
  
___
  
TOBACCO AGE
  
A bill to raise the age from 18 to 21 to buy tobacco products and e-cigarettes was introduced the day before lawmakers were set to adjourn. The bill, from Republican Assemblyman Jim Wheeler, creates an exception for members of the military. The bill, which would not take effect until 2021, was approved by the Assembly on Sunday.
  
___
  
SAME-DAY VOTER REGISTRATION
  
Nevadans may be able to register to vote on Election Day under a bill headed to Sisolak. The measure, from Democratic Assembly Speaker Jason Frierson, would also permit 17-year-olds to vote in a primary election if they would be 18 by a general election. About a dozen states have similar laws.
  
___
  
NATIONAL POPULAR VOTE
  
Sisolak vetoed a measure to change the way the state's Electoral College votes are cast. The bill would have added Nevada to the National Popular Vote compact, meaning the state would pledge to give its Electoral College votes to whichever presidential candidate wins the national popular vote - even if another candidate got more votes in Nevada.
  
___
  
GUNS
  
In their first session since the 2017 mass shooting on the Las Vegas Strip, lawmakers passed stricter gun control measures. One bill bans bump stock devices, which mimic the firing of a fully automatic weapon. A so-called "red flag" law allows guns to be removed from people seen as a threat to themselves or others. In February, Sisolak signed a bill expanding background checks to private gun sales and transfers.
  
___
  
BANNING BROTHELS
  
A proposal by Republican Sen. Joe Hardy to ban legal brothels never received a hearing and failed to clear a key deadline to advance. Hardy argued that brothels, which are only allowed in some counties and mostly operate in rural areas, trap women in an abusive industry. Brothel supporters argued the ban would harm the economies of rural communities and force sex workers into more dangerous, illegal prostitution.
  
___
  
DEATH PENALTY
  
Lawmakers introduced two bills that would have banned the death penalty, but they failed to pass legislative deadlines. The bills came after a death-row inmate killed himself in January amid a legal battle with drug makers who objected to their products being used in a lethal injection.

____

Here are some of the highlights from Sunday's work at the Legislature:
  
EDUCATION FUNDING BILL
  
Both chambers unanimously passed a bill that outlines K-12 education funding for the next biennium.
  
The measure must receive approval from Democratic Gov. Steve Sisolak before becoming law.
  
The bill proposes an average basic support guarantee of $6,218 per pupil for next year's budget, an increase of just over 4% from the current rate. The bill marks the 2021 figure at $6,288.
  
The measure allocates $62.9 million for the Read by Grade 3 program and about $327.2 million for a class-size reduction program.
  
___
  
CAMPAIGN FINANCE BILL
  
A last-minute campaign finance bill cleared its first legislative hurdle.
  
The measure, sponsored by Senate Majority Leader Nicole Cannizzaro, requires labor unions, corporations and other organizations making at least $10,000 in donations a year to report every contribution of $100 or more they make.
  
The legislation also bars public officials from paying themselves a salary with campaign funds. The measure comes months after former Senate Majority Leader Kelvin Atkinson resigned on the Senate floor, announcing he took campaign funds for personal use. He later pleaded guilty in federal court to wire fraud.
  
___
  
COLLECTIVE BARGAINING
  
State workers who've been fighting decades for the right to collectively bargain are close to seeing that become a reality.
  
The Assembly approved the measure, clearing it to head to Sisolak's desk. The governor called for the bill in his State of the State address and is expected to sign it. Union supporters argued the bill would lead to improved services, less turnover and better working conditions.
  
Opponents say the measure could be costly and make it difficult to budget. The bill would cover prison guards, janitors, secretaries and other workers, but teachers would not be included and the measure would not permit a strike.
  
___
  
RAISING SMOKING AGE
  
The Nevada Assembly passed a bill to raise the age for adults to buy tobacco products and e-cigarettes from 18 up to 21. Republican Assemblyman Jim Wheeler's bill was introduced Sunday, the day before lawmakers adjourn for two years. It was passed overwhelmingly by the Assembly and sent to the Senate for consideration.
  
The bill makes an exception for members of the military, leaving the smoking age at 18. Wheeler said those military members would be able to present their military I.D. when purchasing tobacco products. If the bill is passed before midnight Monday and approved by the governor, the law would not take effect until July 2021 -- after the next legislative session.
