There is just one week until the high-stakes midterm elections on Tuesday, Nov. 3.
There are several key House and Senate races that could determine the balance of power in Congress as well as significant races for governor around the country. The elections could ultimately determine how effective President Donald Trump's agenda is in the back half of his second term.
Republican Sen. Lisa Murkowski endorsed Democratic candidate Jonathon S. Kreiss-Tomkins in the Alaska governor's race, his campaign announced Tuesday.
"Our future is too important to be hamstrung by partisan divisions," Murkowski said in a statement. "Alaska needs a serious conversation about our fiscal future, as well as a focus on the cost of energy and growing our economy. I believe Jonathan is committed to working toward solutions that serve all Alaskans, regardless of party."
Murkowski has a history of opposing President Donald Trump and bucking her party.
Trump on Saturday called her the "Republicans' Worst Senator" and "a DISGRACE to Alaska and our Country" over her opposition to the Justice Department's lawsuit seeking to block the certification of the Alaska Senate race if Republican incumbent Sen. Dan Sullivan loses.

President Donald Trump, on his way to a campaign event in Texas on Tuesday, signaled that he would work with Democrats if they regained some control in Congress after the midterms -- but cautioned that he has a "strong veto." He also said he will respect the results of the elections -- but notably added "if they’re honest."
Trump has repeatedly made unfounded claims that there was widespread voter fraud in past elections.
ABC News White House Correspondent Karen Travers asked Trump about his level of concern about GOP Senate candidate Ken Paxton’s chances in the competitive race against Democratic candidate James Talarico.
Trump left the door open to the possibility of Paxton’s loss, saying, "you never know -- it’s politics," but then claimed the Republican would do "very well."

President Donald Trump on Tuesday makes his fourth campaign season (since Labor Day) trip to Texas where he is set to hold two rallies in the state as he and Republicans make their closing arguments in battleground races.
With just one week before Election Day, Trump will attend rallies in Lubbock and Corpus Christi.
All eyes are on the Texas Senate race as Republican Ken Paxton and Democrat James Talarico remain locked in a neck-and-neck contest. Paxton confirmed he will attend and plans to deliver remarks at both rallies. Rep. Monica De La Cruz, who is in a toss-up race in the 15th Congressional District against Tejano musician Bobby Pulido, said she will also be in attendance.
Talarico will also speak at a rally in Lubbock, Texas, on Tuesday, according to a campaign advisory.
More than 20% of registered voters in Texas have voted early.
