Through Think Pink Day, Lauren Blumenfeld and her friends are doing their part to raise money for cancer research.

Blumenfeld, 10, is a fifth-grader at Roland Park Country School in Baltimore. Two years ago, she created Think Pink Day, selling pink ribbons as a fundraiser for breast cancer research. Her grandmother had breast cancer, she told WBAL-TV, and after realizing she probably had friends whose families were dealing with the same thing, she decided school "would be a good place to raise money and awareness."

This month, the students held a bake sale, offering everything from cupcakes to marshmallow pops. All of the money they earned — $1,200 — was donated to the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins, and the kids also made cards for patients. "It makes me feel really happy because I know, one day, we'll make a difference and we'll stop cancer," Blumenfeld said. Catherine Garcia

Senate Majority Leader Mitch McConnell (R-Ky.) on Monday submitted his impeachment trial rules proposal, which calls for a speedy trial.

The resolution will be voted on Tuesday afternoon, and needs a majority to pass the Senate. Under his plan, each side will have 24 hours over two days for opening statements, and senators will have up to 16 hours for questions and four hours of debate. After that, a vote will be held on calling additional witnesses. If other witnesses are called, the Senate will decide if any of them testify publicly.

"Sen. McConnell's resolution is nothing short of a national disgrace," Senate Minority Leader Chuck Schumer (D-N.Y.) said, adding that McConnell "is hell-bent on making it much more difficult to get witnesses and documents and intent on rushing the trial through." This proposal shows that McConnell "doesn't want to hear any of the existing evidence, and he doesn't want to hear any new evidence. A trial where there is no evidence — no existing record, no witnesses, no documents — isn't a trial at all."

Eric Ueland, the White House's legislative affairs director, said President Trump and his team are happy with the proposal, as they are "seeking an acquittal as swiftly as possible." Catherine Garcia

Authorities estimate 22,000 gun-rights advocates attended a rally in Richmond, Virginia, on Monday, to protest proposed gun control legislation.

Ahead of the event, Gov. Ralph Northam (D) declared a state of emergency and temporarily banned people from carrying weapons at the state capitol, citing "credible intelligence" from law enforcement that white supremacists groups would attend the rally and incite violence. Some extremist groups did attend, but the rally was mostly peaceful and there were no reports of violence.

Democrats now control the Statehouse, and have been pushing for new gun regulations, including universal background checks and a ban on military-style rifles. Protesters chanted "We will not comply" and "USA!" and several spoke to reporters about why they came out for the rally. "So many people are misinformed and think you are safer because you take my guns away," participant Jay Lowe told NBC News. "My guns have never killed anybody. And I carry a lot." Catherine Garcia

President Trump's lawyers filed a brief on Monday urging the Senate to dismiss the impeachment charges against him and calling the House's impeachment process a "perversion" of the Constitution, The Associated Press reports.

The 110-page brief calls the House's impeachment case "flimsy," insists Trump did "absolutely nothing wrong," and says he has "been the victim of an illegitimate partisan effort to take him down," The New York Times reports. The House filed two impeachment articles against Trump — abuse of power for withholding aid to Ukraine in order to pressure that country to investigate his political rivals, and obstruction of Congress for blocking the House's impeachment inquiry.

The brief "does not deny that Mr. Trump pressured Ukraine to open investigations into Democrats," the Times writes. Instead it argues that this was within Trump's rights as president. As to the obstruction of Congress article, the lawyers say the president has a right to confidential deliberations.

The Senate trial on Trump's impeachment begins Tuesday. He is just the third sitting president to face such a trial. The Republican-controlled chamber is unlikely to convict him. Jessica Hullinger

Australia just can't catch a break. As wildfires continued to devastate parts of the country, a miles-long dust storm rolled across New South Wales Sunday, blotting out the sun. As CNN reports, the area has been experiencing drought since 2017, so dirt is loose and easily kicked up by high winds.

In other parts of the southeast, thunderstorms over the past two days brought hail stones the size of baseballs, bringing down trees, battering cars and buildings, and leaving thousands of people without electricity, according to The New York Times. There's also been flash flooding. And the Bureau of Meteorology says the storms could continue for another few days. Jessica Hullinger

The number of reported cases of a pneumonia virus spreading through China jumped over the weekend, CNN reports, bringing the total to 201. On Friday, there were 62 reported cases of the illness in China. By Monday, another 139 cases had been reported, and three people had died. The virus, which originated in a wildlife market in the central Chinese city of Wuhan, has also spread to other countries, including South Korea, Thailand, and Japan, CNN reports.

Health authorities say the pathogen is a new strain of coronavirus, which CNN explains is "in the same family of the deadly severe acute respiratory syndrome (SARS)." Its symptoms include fever and shortness of breath, QZ reports.

The outbreak comes as China prepares to celebrate the Lunar New Year. Last year, CNN estimates 7 million people traveled outside the country for the occasion. South Korea has been screening travelers arriving from Wuhan for fever at Seoul's Incheon International Airport. Some airports in the U.S. are doing the same. However, CNN points out that "a new study by Imperial College London suggests the number of infections in Wuhan is likely to have been grossly underestimated."

"The detection of three cases outside China is worrying," Neil Ferguson, a disease outbreak scientist at Imperial College London, said. "We calculate, based on flight and population data, that there is only a 1 in 574 chance that a person infected in Wuhan would travel overseas before they sought medical care. This implies there might have been over 1,700 cases in Wuhan so far." Jessica Hullinger

Virginia officials braced for possible violence as buses packed with gun-rights advocates began arriving in the capital city of Richmond for a large Monday rally where authorities fear an outburst of violence by white supremacists, the Richmond Times-Dispatch reports. Gov. Ralph Northam (D) last week declared a state of emergency in Richmond, and temporarily barred people from carrying firearms on the grounds of the state capitol. Gun-rights advocates, who are planning a peaceful rally, challenged the ban in court, but lost. "Virginians have the right to assemble. And I believe in the right to bear arms. But what we have seen and heard in recent weeks has the potential to go far beyond these constitutionally protected rights," Northam said last week. "We are seeing threats of violence." Organizers said Monday's protests against possible new gun-control legislation could draw 50,000 people, the Richmond Times-Dispatch reports. Harold Maass
