The head of the U.S. Capitol Police will resign effective Jan. 16 following the breach of the Capitol by a pro-Trump mob.Chief Steven Sund said Thursday that police had planned for a free speech demonstration and did not expect the violent attack. He said it was unlike anything he’d experienced in his 30 years in law enforcement.He resigned Thursday after House Speaker Nancy Pelosi called on him to step down. His resignation was confirmed to The Associated Press by a person familiar with the matter who was not authorized to speak publicly.The breach halted the effort by Congress to certify President-elect Joe Biden’s victory. Protesters stormed the building and occupied for hours. The lawmakers eventually returned and finished their work.

A police officer has died from injuries sustained as President Donald Trump's supporters stormed the Capitol, a violent siege that is forcing hard questions about the defeated president's remaining days in office and the ability of the Capitol Police to secure the area.The U.S. Capitol Police said in a statement that Officer Brian D. Sicknick was injured “while physically engaging with protesters" during the Wednesday riot. He is the fifth person to die because of the melee.The rampage that has shocked the world and left the country on edge forced the resignations of three top Capitol security officials over the failure to stop the breach. It led lawmakers to demand a review of operations and an FBI briefing over what they called a “terrorist attack.” And it is prompting a broader reckoning over Trump’s tenure in office and what comes next for a torn nation.Protesters were urged by Trump during a rally near the White House earlier Wednesday to head to Capitol Hill, where lawmakers were scheduled to confirm Biden’s presidential victory. The mob swiftly broke through police barriers, smashed windows and paraded through the halls, sending lawmakers into hiding.Five have died because of the Capitol siege. One protester, a white woman, was shot to death by Capitol Police, and there were dozens of arrests. Three other people died after “medical emergencies” related to the breach.Despite Trump’s repeated claims of voter fraud, election officials and his own former attorney general have said there were no problems on a scale that would change the outcome. All the states have certified their results as fair and accurate, by Republican and Democratic officials alike.Sen. Ben Sasse, R-Neb., said news of the police officer’s death was “gut-wrenching.”“None of this should have happened,” Sasse said in a statement. “Lord, have mercy.”Sicknick had returned to his division office after the incident and collapsed, the statement said. He was taken to a local hospital where he died on Thursday.Two House Democrats on committees overseeing the Capitol police budgets said those responsible need to be held to answer for the “senseless” death."We must ensure that the mob who attacked the People’s House and those who instigated them are held fully accountable,” said Rep. Rosa DeLauro, D-Ct., and Rep. Tim Ryan, D-Ohio. in a statement.Earlier Thursday, House Speaker Nancy Pelosi said any remaining day with the president in power could be “a horror show for America.” Likewise, Senate Democratic leader Chuck Schumer said the attack on the Capitol was “an insurrection against the United States, incited by the president," and Trump must not stay in office “one day” longer.Pelosi and Schumer called for invoking the 25th Amendment to the Constitution to force Trump from office before President-elect Joe Biden is inaugurated on Jan. 20. Schumer said he and Pelosi tried to call Vice President Mike Pence early Thursday to discuss that option but were unable to connect with him.At least one Republican lawmaker joined the effort. The procedure allows for the vice president and a majority of the Cabinet to declare the president unfit for office. The vice president then becomes acting president.Pelosi said if the president’s Cabinet does not swiftly act, the House may proceed to impeach Trump. Trump, who had repeatedly refused to concede the election, did so in a late Thursday video from the White House vowing a “seamless transition of power.”Two Republicans who led efforts to challenge the election results, Ted Cruz of Texas and Josh Hawley of Missouri, faced angry peers in the Senate. Cruz defended his objection to the election results as “the right thing to do” as he tried unsuccessfully to have Congress launch an investigation. In the House, Republican leaders Rep. Kevin McCarthy of California and Rep. Steve Scalise of Louisiana joined in the failed effort to overturn Biden’s win by objecting to the Electoral College results.With tensions high, the Capitol shuttered and lawmakers not scheduled to return until the inauguration, an uneasy feeling of stalemate settled over a main seat of national power as Trump remained holed up at the White House.The social media giant Facebook banned the president from its platform and Instagram for the duration of Trump's final days in office, if not indefinitely, citing his intent to stoke unrest. Twitter had silenced him the day before.Facebook founder Mark Zuckerberg said “the shocking events" make it clear Trump “intends to use his remaining time in office to undermine the peaceful and lawful transition of power.”U.S. Capitol Police Chief Steven Sund, under pressure from Schumer, Pelosi and other congressional leaders, was forced to resign. Senate Majority Leader Mitch McConnell asked for and received the resignation of the Sergeant at Arms of the Senate, Michael Stenger, effective immediately. Paul Irving, the longtime Sergeant at Arms of the House, also resigned.Sund had defended his department’s response to the storming of the Capitol, saying officers had “acted valiantly when faced with thousands of individuals involved in violent riotous actions.” Washington Mayor Muriel Bowser called the police response “a failure.”Lawmakers from both parties pledged to investigate and questioned whether a lack of preparedness allowed a mob to occupy and vandalize the building. The Pentagon and Justice Department had been rebuffed when they offered assistance.Black lawmakers, in particular, noted the way the mostly white Trump supporters were treated.Newly elected Rep. Cori Bush, D-Mo., said if “we, as Black people did the same things that happened ... the reaction would have been different, we would have been laid out on the ground.” The protesters ransacked the place, taking over the House area and Senate chamber and waving Trump, American and Confederate flags. Outside, they scaled the walls and balconies.Rep. Val Demings, D-Fla., a former police chief, said it was “painfully obvious” that Capitol police “were not prepared.”

Never did Karlin Younger expect an everyday chore to spark a federal investigation. But the lunch break she decided to use to do laundry on Jan. 6 did just that in our nation's Capitol."I was doing a now infamous load of laundry, just changing it over from the washer to the dryer," she recalled.It was that load, the Wisconsin native who now lives and works in D.C., was taking back to her building when she looked down and saw something odd."My first reaction was, 'This has got to be trash,' until I kind of leaned closer and saw that it was, in fact, something that looked like a bomb. She noticed the piping, wires and a timer pointed to the number 20. "You're on that edge of, 'I don't want to bother anybody, I want to make sure this is real,'" she recalled from her home in Washington. "You don't want to go down as the person who evacuates a city block for a hoax. But at the same time, there was just enough of that gut instinct that said, 'This isn't a place you put a hoax, I have to have somebody check this out.'"She decided to alert a security guard nearby. The bomb had been placed next to the headquarters of the Republican National Committee.Younger would later learn it was the first of two pipe bombs discovered that day, the same day a mob attacked the United States Capitol in support of President Donald Trump and his false claims alleging the election was "stolen."Investigators found the other potentially deadly device near the Democratic headquarters about a quarter-mile south of Younger's building. Federal investigators published a wanted poster with an image of the person they believe planted both bombs. The FBI is offering a $50,000 reward to find the person.For younger, the personal reward was knowing she was in a position to help."I mostly say I just got really lucky," she said. "The lesson I've learned is really to just trust your gut and if you see something, say something."
