The Senate Republicans issued a statement in support of Pelosi.
It shows how challenging China has become with bipartisan support.
Beijing had threatened to cut off Taiwan from the rest of the world.
McConnell and over two dozen other Senate Republicans issued a rare statement of support for Pelosi as she traveled to Taiwan.
Speaker of the House of Representatives Nancy Pelosi is on a trip to Taiwan.
"For decades, members of the United States Congress, including previous Speaker of the House, have traveled to Taiwan." The travel is consistent with the US' One China policy. The Taiwan Relations Act is something we are committed to more than ever.
Despite historic political divisions, China has become a bipartisan issue in the US.
The US gives diplomatic recognition to Beijing's position that there is only one Chinese government under the One China policy. The US does not have official diplomatic relations with Taiwan.
The US has a strong relationship with Taiwan. The Taiwan Relations Act requires the US to give Taiwan defensive weapons. Taiwan gets most of its arms from the US.
China warned of a possible military response ahead of Pelosi's visit. The Chinese government believes that Pelosi's trip to the self-governing island democracy undermines the One China policy.
Pelosi's trip undermines peace and stability across the Taiwan Strait and sends a wrong signal to the Taiwan independence movement, according to the Foreign Ministry.
Pelosi wrote that visiting Taiwan is an important sign of America's commitment to democracy.
"We can't stand by as the Chinese Communist Party threatens Taiwan and democracy itself," Pelosi said. It is important that America and our allies make clear that we never give in to autocrats as Russia wages its illegal war against Ukraine.
The One China policy was not violated by Pelosi's trip to Taiwan.
China is holding live-fire military exercises close to Taiwan.
