Former US President Donald Trump has lashed out at Republicans, calling them "weak, foolish and dumb" as his preferred candidate in a Texas election loses.
On Thursday the US Senate, with the support of 48 Democrats, two independents and 17 Republicans, progressed a key infrastructure Bill worth about US$1 trillion.
However, the decision by some Republicans to support the measure hasn't been well received by Trump.
"Hard to believe our Senate Republicans are dealing with the Radical Left Democrats in making a so-called bipartisan bill on 'infrastructure,' with our negotiators headed up by SUPER RINO Mitt Romney," Trump said in a statement.
"This will be a victory for the Biden Administration and Democrats, and will be heavily used in the 2022 election. It is a loser for the USA, a terrible deal, and makes the Republicans look weak, foolish, and dumb. It shouldn't be done."
He said "patriots will never forget" and that if the deal happens, "lots of primaries will be coming your way".
But it doesn't look so good for the Republicans who are aligning themselves with the former President. His preferred candidate for a US House seat in Texas was projected to lose a special runoff election on Tuesday, defeated by a fellow Republican, the Texas Tribune newspaper reports.
Susan Wright, a 58-year-old Republican activist whom Trump endorsed in April, is projected to lose to Texas state legislator Jake Ellzey in Texas' 6th congressional district.
"Ellzey's victory suggests a Trump endorsement may not be all that is cracked up to be, while also highlighting Wright's weakness as a candidate and the ineffectual campaign she and her advisors ran, hoping to coast to victory based on Trump's endorsement," said Mark Jones, a Rice University political science professor, according to Retuers.
The infrastructure agreement includes $110 billion for roads, $73 billion for power grid spending, $66 billion for railways, $65 billion to expand broadband access, $55 billion for clean drinking water, $50 billion for environmental resiliency, $39 billion for public transit and $25 billion for airports.
