The U.S. has coordinated with Pakistan, Uzbekistan and Tajikistan about facilitating cross-border travel for U.S. citizens -- including having U.S. consular officials on those countries' side of the border with Afghanistan to receive evacuees, Secretary of State Antony Blinken told senators on Tuesday.

At a prior hearing with House lawmakers on Monday, Blinken confirmed one American family crossed into Uzbekistan, but before the Senate Foreign Relations Committee he acknowledged for the first time they've coordinated with all three countries.

While some $80 billion of U.S. equipment over the last 15 years that was provided to the Afghan government has fallen into Taliban hands, Blinken claimed much of it is inoperable or will become inoperable because it requires maintenance, adding, "None of it possesses a strategic threat to us or Afghanistan's neighbors."

Secretary of State Antony Blinken has largely stuck to his talking points before the Senate Foreign Relations Committee on Tuesday under criticism from lawmakers on both sides of the aisle on the U.S. evecautions mission and military withdrawal.

"The administration patting itself on the back for this evacuation is like an arsonist taking credit for saving people from the burning building he just set on fire," said ranking member, Sen. Jim Risch, R-Ind., adding Biden's withdrawal "left Afghanistan in total disarray."

Like Risch, Sen. Ron Johnson, R-Wisc., was relatively rough in his questioning, and at one point interrupted Blinken from answering, mockingly dismissing his "bureaucratic speak." Sen. John Barrasso, R-Wyo., blasted Blinken's leadership and called the mission an "epic failure."

Sen. Jeanne Shaheen, D-N.H., the committee's only woman, pressed Blinken about the rights of women and girls in Afghanistan under Taliban rule, recalling her tough questioning of former Secretary of State Mike Pompeo, who dismissed concerns about the issue.

"There's a lot of regret and recriminations to go around," she told her Senate colleagues. "But let's stop the hypocrisy about who's to blame. There are a lot of people to blame, and we all share in it."

Under her questioning, Blinken announced that he is tasking a senior official with overseeing the rights of women, girls and other minorities in Afghanistan as a point person.

Secretary of State Antony Blinken could not provide an exact number of Americans or Special Immigrant Visa holders left in Afghanistan in a heated Senate hearing on Tuesday.

He said the number of Americans that still want to evacuate is "about 100," as he had in testimony on Monday before House lawmakers.

"It is hard to give a real-time number at any given moment because it is very fluid," Blinken said.

Pressed by Sen. Mitt Romney, R-Utah, on SIV applicants left behind, and whether that number was in the "tens of thousands," Blinken said the State Department is "still tabulating" it as some applicants are in transit and others are still being processed. The State Department has previously acknowledged that at least thousands are still in the country.

Blinken continued to blame the Trump administration for giving Biden a May 1 deadline to withdraw, but not a plan to do so, and said that under the Trump administration’s State Department "not a single" SIV application had been processed in nine months from March 2020.

Noting that Biden did push the withdrawal date to Aug. 31, Romney asked Blinken why not move the withdrawal date to accommodate the "moral commitment" the U.S. made to Americans, permanent residents and vulnerable Afghans who worked with Defense and State officials.

"The military told us that in order to do its retrograde, it's drawdown from Afghanistan, in a safe and ordinarily way, it needed three to four months. That's why we pushed to move beyond May 1 and to get to the end of August, early September," Blinken said.

"Our expectation was that beyond August 31, beyond the military drawdown, the government, the security forces, were going to remain in control of Kabul," Blinken continued. "What we did not anticipate was that 11-day collapse of the government security forces. That's what changed everything."

Secretary of State Antony Blinken's second day of tough questions on Capitol Hill has begun -- and already the Democratic chair of the Senate Foreign Relations Committee has been highly critical.

Sen. Bob Menendez, D-N.J., called Biden's execution of the U.S. withdrawal "clearly fatally flawed" and said information from State, the Pentagon, and the White House during the operations was "vague or contradictory."

"Doing the right thing in the wrong way can end up being the wrong thing," Menendez added. "There has to be accountability."

Menendez also went after Defense Secretary Lloyd Austin -- saying he declined to appear before the committee with Blinken. Menendez said he was "very disappointed" and may use the committee's subpoena power to have him and others responsible over the last 20 years appear for testimony. Austin is scheduled to appear on Capitol Hill next week.

But like Democrats on Monday, Menendez laid the blame on several people -- "successive administrations" making the "same mistakes repeatedly" and lying to Congress about the staying power of Afghan government institutions. He cited the "surrender deal negotiated" by former President Donald Trump, adding it was "built on a bed of lies."
